foundation_core 0.0.3

//! JS event loop yield backends.
//!
//! Selects and exposes the correct `JSThreadYielder` implementation based on
//! feature flags. The public API is always `JSThreadYielder` regardless of
//! which feature is active.
//!
//! Priority: `js-foundation-wasm` > `js-wasmbindgen` (when both are enabled,
//! foundation-wasm wins).

// These JS event-loop yield backends are inherently single-threaded-wasm: they call
// host FFI (`register_schedule`/`requestAnimationFrame`-style yielding) and use
// closures that aren't `Send`/`Sync`. They are gated to wasm targets so a native
// build with one of these features doesn't try to compile wasm-only code (the
// native default is `NoThreadController` — see `single/mod.rs`).
