//! Library crate exposing gvsn's internals for the benchmark targets under
//! `benches/`. The `gvsn` binary (`src/main.rs`) is a thin wrapper around
//! [`run`]; every module listed here is the exact same code that ships in
//! the binary, just also reachable from outside `src/main.rs`.
//!
//! This crate is not published or intended for use as a dependency by other
//! projects - it exists solely so `cargo bench` has something to link
//! against.
