unity-solution-generator 0.1.1

//! Shared fixture builder for benches. Synthesises a Unity-shaped project tree.
//!
//! Used by all three benches; we avoid `mod common` in each bench file because
//! Cargo treats `benches/<name>.rs` as separate crates and resolving sibling
//! modules requires `path = ...` declarations. Instead each bench declares this
//! file via `#[path = "common.rs"] mod common;`.
