Module task 

Tasks — the unit the scheduler multiplexes.

A task is a small state machine: each poll advances it until it next wants to block (on a channel, a select, or a timer), yield, spawn, or exit. The scheduler drives poll, parks the task on blocking steps, and resumes it (delivering any value) when the block clears. The interpreter and VM each implement Task over their own continuation; the toy tasks in the tests implement it by hand.

Structs

TaskCtx

Per-poll context: what the task was resumed with.

TaskId

A scheduler-assigned task handle.

Enums

SelectArm

One arm of a Select (Await the first of:).

TaskStep

What a task asks the scheduler to do after a poll.

Traits

Task

A schedulable unit of work. 't ties any spawned children to the lifetime of borrowed data the task closes over (e.g. the interpreter’s borrowed AST).
