Pull request description:

  The first 8 patches clear clippy warnings. Next we add a CI job to run clippy. Finally we add a `githooks` directory that includes running clippy, also adds a section to the README on how to use the githooks. This is identical to the text in the [open PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/1044) on `rust-bitcoin` that adds githooks _without_ yet adding clippy.

  **Note**: The new clippy CI job runs and is green :)

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.
