secp256k1-sys
|
|
=============
|
|
|
|
|
|
This crate provides Rust definitions for the FFI structures and methods.
|
|
|
|
|
|
## Vendoring
|
|
|
|
The default build process is to build using the vendored libsecp256k1 sources in
|
|
the depend folder. These sources are prefixed with a special
|
|
rust-secp256k1-sys-specific prefix `rustsecp256k1_v1_2_3_`.
|
|
|
|
This prefix ensures that no symbol collision can happen:
|
|
- when a Rust project has two different versions of rust-secp256k1 in its
|
|
depepdency tree, or
|
|
- when rust-secp256k1 is used for building a static library in a context where
|
|
existing libsecp256k1 symbols are already linked.
|
|
|
|
To update the vendored sources, use the `vendor-libsecp.sh` script:
|
|
|
|
```
|
|
$ ./vendor-libsecp.sh depend <version-code> <rev>
|
|
```
|
|
|
|
- Where `<version-code>` is the secp256k1-sys version number underscored: `0_1_2`.
|
|
- Where `<rev>` is the git revision of libsecp256k1 to checkout.
|
|
|
|
|
|
## Linking to external symbols
|
|
|
|
If you want to compile this library without using the bundled symbols (which may
|
|
be required for integration into other build systems), you can do so by adding
|
|
`--cfg=rust_secp_no_symbol_renaming'` to your `RUSTFLAGS` variable.
|
|
|
|
## Minimum Supported Rust Version
|
|
|
|
This library should always compile with any combination of features on **Rust 1.48.0**.
