With rust-script Rust files and expressions can be executed just like a shell or Python script. Features include: - Caching compiled artifacts for speed. - Reading Cargo manifests embedded in Rust scripts. - Supporting executable Rust scripts via Unix shebangs and Windows file associations. - Using expressions as stream filters (i.e. for use in command pipelines). - Running unit tests and benchmarks from scripts. - Custom templates for command-line expressions and filters.
