OpenCut/rust

rust/

Shared Rust crates that power OpenCut across platforms (web via WASM, desktop natively).

Adding a new crate

1. Create it under rust/crates/
2. Add bridge as a dependency
3. Annotate public functions with #[export]

How #[export] works

use bridge::export;

#[export]
pub fn round_to_frame(time: f64, fps: f64) -> f64 {
    (time * fps).round() / fps
}

Without the wasm feature, the macro is a no-op. With --features wasm, it expands to:

#[wasm_bindgen(js_name = "roundToFrame")]
pub fn round_to_frame(time: f64, fps: f64) -> f64 { ... }

Desktop uses the crates directly as Cargo dependencies.

Testing

cargo test -p <crate>
