# Class LittleGhost::Instrumentation::Handle

Documentation version: Edge

Canonical HTML: https://littleghostai.org/docs/LittleGhost/Instrumentation/Handle.html

A Handle represents work between Instrumentation.start and #finish.

Non-detached handles are fiber-owned and must finish in LIFO order after their
children. Detached handles may finish outside the creating fiber but still
cannot finish while local children remain active.
