profiler

runtime-builtins.d.ts

fino:profiler — Rust-backed CPU profiler controls.

The profiler module starts and stops V8 CPU profile capture from JS code. stopProfiling() returns the serialized profile bytes; callers choose where to store or upload them.

Functions

`function startProfiling(name?: string): void`

Start collecting a named CPU profile.

`function stopProfiling(name?: string): Uint8Array`

Stop collecting a named CPU profile and return its serialized bytes.
