This commit updates the optional rustls-ffi librustls dependency from 0.12.0 to 0.13.0. This version is based on the latest available rustls release (0.23.4). The breaking API changes from 0.12.0 to 0.13.0 are in API surface unused by curl, so this is an in-place update without any code changes. The `RUSTLS.md` documentation is updated to reflect the new version in use, and to clarify that `cbindgen` isn't required to build `librustls` - it's only used by developers to update the vendored `rustls.h` header file maintained upstream. Closes #13238

# Rustls
|
|
|
|
[Rustls is a TLS backend written in Rust](https://docs.rs/rustls/). Curl can
|
|
be built to use it as an alternative to OpenSSL or other TLS backends. We use
|
|
the [rustls-ffi C bindings](https://github.com/rustls/rustls-ffi/). This
|
|
version of curl depends on version v0.13.0 of rustls-ffi.

# Building with rustls
|
|
|
|
First, [install Rust](https://rustup.rs/).
|
|
|
|
Next, check out, build, and install the appropriate version of rustls-ffi:
|
|
|
|
% git clone https://github.com/rustls/rustls-ffi -b v0.13.0
|
|
% cd rustls-ffi
|
|
% make
|
|
% make DESTDIR=${HOME}/rustls-ffi-built/ install
|
|
|
|
Now configure and build curl with rustls:
|
|
|
|
% git clone https://github.com/curl/curl
|
|
% cd curl
|
|
% autoreconf -fi
|
|
% ./configure --with-rustls=${HOME}/rustls-ffi-built
|
|
% make
|
