Modules

AnyTask

This is a slower wrapper around a function pointer. Prefer adding a task type directly to Task instead of using this.

AnyTaskWithExtraContext

This is AnyTask except it gives you two pointers instead of one. Generally, prefer jsc.Task instead of this.

AutoFlusher

ConcurrentTask

A task that runs concurrently in the work pool.

ConcurrentWakeup

Process-global liveness registry for cross-thread wakeups of per-thread MiniEventLoops.

DeferredTaskQueue

Sometimes, you have work that will be scheduled, cancelled, and rescheduled multiple times The order of that work may not particularly matter.

EventLoopTimer

ManagedTask

This is a slow, dynamically-allocated one-off task Use it when you can’t add to jsc.Task directly and managing the lifetime of the Task struct is overly complex

MiniEventLoop

MiniEventLoop: A lightweight event loop for non-JavaScript contexts

SpawnSyncEventLoop

Isolated event loop for spawnSync operations.

any_event_loop

Macros

impl_timer_owner

Stamp out one unsafe fn $method(*const EventLoopTimer) -> *mut Self per (method => field) pair: each recovers the embedding owner from a pointer to the named intrusive EventLoopTimer slot — Rust’s typed analogue of Zig’s inline @fieldParentPtr("$field", t).

link_impl_JsEventLoop

JsEventLoop

Enums

ErasedJsError

Historical low-tier alias for bun_jsc::JsError. The canonical enum now lives in bun_core (tier-0), so this is a straight re-export — the old “erased discriminant” split exists only to keep call sites compiling. bun.JSError — the canonical JS error union (error{JSError, OutOfMemory, JSTerminated} in Zig). Tier-0 so every layer of the runtime can name it directly; bun_jsc re-exports it as bun_jsc::JsError and bun_event_loop re-exports it as ErasedJsError for historical call sites.
