Note that only double precision routines are provided by R. The build script for this particular crate owes a lot to libR-sys of the extendr project, with sections lifted from there, in addition to new code.

Use of this package is explained here, specifically under the Sources section.

This library can be installed as usual. It can also built from source but has extra platform-specific dependencies for Windows such as msys2, typically provided by Rtools.

Two components are required to build the library:

1. R: It needs to be installed and available in the search path. On Windows, the Rtools binaries are also expected to be on the search path.
2. Rust: It is recommended to install Rust using rustup; search path should include Rust binaries.

Once R and Rust are configured, the library can be easily built:

# macOS & Linux
cargo build

# Windows
cargo build --target x86_64-pc-windows-gnu

To test the build, run cargo test.

# macOS & Linux
cargo test

# Windows
cargo test --target x86_64-pc-windows-gnu
