tower-serve-embedded-build

Build-time helper for tower-serve-embedded.

Call it from your crate's build.rs. It walks an asset directory, content-hashes every file with BLAKE3, detects MIME types, and generates a Rust file (in OUT_DIR) containing the embedded manifest (ASSETS) and a compile-time asset! macro. There are no proc macros — the generated code is plain data plus a tiny macro_rules!, so IDE support stays sharp.

# Cargo.toml
[build-dependencies]
tower-serve-embedded-build = "0.1"

// build.rs
fn main() {
    tower_serve_embedded_build::Builder::new("assets") // dir relative to your crate root
        // .immutable_dir("lib")                        // already-versioned deps: serve as-is
        // .hash_length(16)                             // hash chars in filenames/ETags
        .emit()
        .unwrap();
}

Then pull the generated code into your crate with tower_serve_embedded::embed!(), which brings the ASSETS static and the crate-local asset! macro into scope.

See the tower-serve-embedded crate for the full story, the runtime tower::Service, and runnable axum/actix/warp examples.
