# Licensing
|
|
|
|
Lexical is dual licensed under the Apache 2.0 license as well as the MIT
|
|
license. See the LICENCE-MIT and the LICENCE-APACHE files for the licenses.
|
|
|
|
Other licensing terms may apply, as described in depth below for various features and functionality. All assume use of `lexical` or `lexical-core`.
|
|
|
|
## `write-floats, not(compact)`
|
|
|
|
`lexical-write-float/src/algorithm.rs` is a direct port of the reference C++ implementation of Dragonbox, found [here](https://github.com/jk-jeon/dragonbox/).
|
|
This code (used if the `write-floats` feature is enabled and the `compact` feature is disabled) is subject to a [Boost Software License](https://github.com/jk-jeon/dragonbox/blob/71993f55067a89f4b4e27591605e21521f5c61be/LICENSE-Boost) and a modified [Apache2 license](https://github.com/jk-jeon/dragonbox/blob/71993f55067a89f4b4e27591605e21521f5c61be/LICENSE-Apache2-LLVM), shown in the [Boost Software License](#boost-software-license) and [Apache2 With LLVM Exceptions](#apache2-with-llvm-exceptions) sections below.
|
|
|
|
## `write-floats, compact`
|
|
|
|
`lexical-write-float/src/compact.rs` is a direct port of a C++ implementation of the Grisu algorithm, found [here](https://github.com/night-shift/fpconv/).
|
|
This code (used if both the `write-floats` and `compact` features are enabled) is subject to a [MIT License](https://github.com/night-shift/fpconv/blob/dfeb7e938fb85fb5eca130b84f856705ced75012/license), shown in the [fpconv License](#fpconv-license) section below.
|
|
|
|
## `write-floats, radix`
|
|
|
|
`lexical-write-float/src/radix.rs` is adapted from the V8 implementation found [here](). This code (used if both the `parse-floats` and `radix` features are enabled) is subject to a [3-clause BSD license](https://github.com/v8/v8/blob/f80bfeaf0792652bfbc1f174d5a7b8ab8bc0cbbd/LICENSE.v8), shown in the [V8 License](#v8-license) section below.
|
|
|
|
## `parse-floats, compact`
|
|
|
|
`lexical-parse-float/src/bellerophon.rs` is loosely based off the Golang implementation,
|
|
found [here](https://github.com/golang/go/blob/b10849fbb97a2244c086991b4623ae9f32c212d0/src/strconv/extfloat.go). This code (used if both the `parse-floats` and `compact` features are enabled) is subject to a [3-clause BSD license](https://github.com/golang/go/blob/b10849fbb97a2244c086991b4623ae9f32c212d0/LICENSE), shown in the [Go License](#go-license) section below.

|
|
“Derivative Works” shall mean any work, whether in Source or Object form, that
|
|
is based on (or derived from) the Work and for which the editorial revisions,
|
|
annotations, elaborations, or other modifications represent, as a whole, an
|
|
original work of authorship. For the purposes of this License, Derivative Works
|
|
shall not include works that remain separable from, or merely link (or bind by
|
|
name) to the interfaces of, the Work and Derivative Works thereof.

#### 2. Grant of Copyright License
|
|
|
|
Subject to the terms and conditions of this License, each Contributor hereby
|
|
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
|
|
irrevocable copyright license to reproduce, prepare Derivative Works of,

such license applies only to those patent claims licensable by such Contributor
|
|
that are necessarily infringed by their Contribution(s) alone or by combination
|
|
of their Contribution(s) with the Work to which such Contribution(s) was
|
|
submitted. If You institute patent litigation against any entity (including a
|
|
cross-claim or counterclaim in a lawsuit) alleging that the Work or a
|
|
Contribution incorporated within the Work constitutes direct or contributory
|
|
patent infringement, then any patent licenses granted to You under this License
|
|
for that Work shall terminate as of the date such litigation is filed.
|
|
|
|
#### 4. Redistribution
|
|
|
|
You may reproduce and distribute copies of the Work or Derivative Works thereof
|
|
in any medium, with or without modifications, and in Source or Object form,
|
|
provided that You meet the following conditions:
|
|
|
|
* **(a)** You must give any other recipients of the Work or Derivative Works a copy of
|
|
this License; and
|
|
* **(b)** You must cause any modified files to carry prominent notices stating that You
|
|
changed the files; and
|
|
* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
|
|
all copyright, patent, trademark, and attribution notices from the Source form
|
|
of the Work, excluding those notices that do not pertain to any part of the
|
|
Derivative Works; and
|
|
* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
|
|
Derivative Works that You distribute must include a readable copy of the
|
|
attribution notices contained within such NOTICE file, excluding those notices
|
|
that do not pertain to any part of the Derivative Works, in at least one of the
|
|
following places: within a NOTICE text file distributed as part of the
|
|
Derivative Works; within the Source form or documentation, if provided along
|
|
with the Derivative Works; or, within a display generated by the Derivative
|
|
Works, if and wherever such third-party notices normally appear. The contents of
|
|
the NOTICE file are for informational purposes only and do not modify the
|
|
License. You may add Your own attribution notices within Derivative Works that
|
|
You distribute, alongside or as an addendum to the NOTICE text from the Work,
|
|
provided that such additional attribution notices cannot be construed as
|
|
modifying the License.
|
|
|
|
You may add Your own copyright statement to Your modifications and may provide
|
|
additional or different license terms and conditions for use, reproduction, or
|
|
distribution of Your modifications, or for any such Derivative Works as a whole,
|
|
provided Your use, reproduction, and distribution of the Work otherwise complies
|
|
with the conditions stated in this License.
|
|
|
|
#### 5. Submission of Contributions
|
|
|
|
Unless You explicitly state otherwise, any Contribution intentionally submitted
|
|
for inclusion in the Work by You to the Licensor shall be under the terms and
|
|
conditions of this License, without any additional terms or conditions.
|
|
Notwithstanding the above, nothing herein shall supersede or modify the terms of
|
|
any separate license agreement you may have executed with Licensor regarding
|
|
such Contributions.
|
|
|
|
#### 6. Trademarks
|
|
|
|
This License does not grant permission to use the trade names, trademarks,
|
|
service marks, or product names of the Licensor, except as required for
|
|
reasonable and customary use in describing the origin of the Work and
|
|
reproducing the content of the NOTICE file.
|
|
|
|
#### 7. Disclaimer of Warranty
|
|
|
|
Unless required by applicable law or agreed to in writing, Licensor provides the
|
|
Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
|
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
|
|
including, without limitation, any warranties or conditions of TITLE,
|
|
NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
|
|
solely responsible for determining the appropriateness of using or
|
|
redistributing the Work and assume any risks associated with Your exercise of
|
|
permissions under this License.
|
|
|
|
#### 8. Limitation of Liability
|
|
|
|
In no event and under no legal theory, whether in tort (including negligence),
|
|
contract, or otherwise, unless required by applicable law (such as deliberate
|
|
and grossly negligent acts) or agreed to in writing, shall any Contributor be
|
|
liable to You for damages, including any direct, indirect, special, incidental,
|
|
or consequential damages of any character arising as a result of this License or
|
|
out of the use or inability to use the Work (including but not limited to
|
|
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
|
|
any and all other commercial damages or losses), even if such Contributor has
|
|
been advised of the possibility of such damages.
|
|
|
|
#### 9. Accepting Warranty or Additional Liability
|
|
|
|
While redistributing the Work or Derivative Works thereof, You may choose to
|
|
offer, and charge a fee for, acceptance of support, warranty, indemnity, or
|
|
other liability obligations and/or rights consistent with this License. However,
|
|
in accepting such obligations, You may act only on Your own behalf and on Your
|
|
sole responsibility, not on behalf of any other Contributor, and only if You
|
|
agree to indemnify, defend, and hold each Contributor harmless for any liability
|
|
incurred by, or claims asserted against, such Contributor by reason of your
|
|
accepting any such warranty or additional liability.

### LLVM Exceptions to the Apache 2.0 License
|
|
|
|
As an exception, if, as a result of your compiling your source code, portions
|
|
of this Software are embedded into an Object form of such source code, you
|
|
may redistribute such embedded portions in such Object form without complying
|
|
with the conditions of Sections 4(a), 4(b) and 4(d) of the License.
|
|
|
|
In addition, if you combine or link compiled forms of this Software with
|

software that is licensed under the GPLv2 ("Combined Software") and if a
|
|
court of competent jurisdiction determines that the patent provision (Section
|
|
3), the indemnity provision (Section 9) or other Section of the License
|
|
conflicts with the conditions of the GPLv2, you may retroactively and
|
|
prospectively choose to deem waived or otherwise exclude such Section(s) of
|
|
the License, but only in their entirety and only with respect to the Combined
|
|
Software.
