Enum WorkerScriptLoadState

pub enum WorkerScriptLoadState {

Expand description

Used for CDP observability and lifecycle management. The Worker script loading process has these states:

  1. Pending — URL resolved, fetch not yet started
  2. Fetching — HTTP request in progress (DF-WK-2: “global.fetch”)
  3. Validating — Response received, MIME type check (DF-WK-2: “JS MIME 校验”)
  4. Decoding — UTF-8 decode of response body (DF-WK-2: “UTF-8 解码”)
  5. Compiling — SpiderMonkey compilation (DF-WK-2: “Classic/Module 编译”)
  6. Ready — Script compiled, ready for Worker thread evaluation
  7. Failed — Error at any stage (network/MIME/decode/compile)

impl<T> AsCtxPtr for T

fn as_ctx_ptr(&self) -> *mut Self
where Self: Sized,

self’s address as *mut Self for deferred-task / scopeguard / ref_guard ctx slots. The closures/trampolines deref it as shared (&*p) — every method they reach is &self post-R-2, so no write provenance is required; the *mut spelling is purely to match the existing DerefOnDrop / HasAutoFlush / RefCount ABI.
