Enum ResumeKind 

pub enum ResumeKind {
    Nothing,
    Spawn {
        func: FuncIdx,
        args: Vec<RtPayload>,
        priority: u8,
        is_main: bool,
    },

    SpawnedHandle(TaskId),
}

How a worker should (re)enter a task body on its next poll. Every variant is Send (FuncIdx is u16, RtPayload is Send, ids are Copy).

Variants

Nothing

First entry / a block that yields no value (Send/Close/Yield/Sleep).

Spawn

Fresh spawn: build the body from this function + materialised args. is_main distinguishes the program’s root task (whose body is the top-level program, not a spawned function) so the builder positions it correctly.

Fields

func: FuncIdx

args: Vec<RtPayload>

priority: u8

is_main: bool

Payload(RtPayload)

Resume a pinned continuation with a delivered value (Recv/TryRecv/Await).

Select

Resume a Select winner: the winning arm index + its (recv) payload.

Fields

arm: usize

payload: RtPayload

NewChan(ChanId)

Resume after NewChan with the freshly-created channel id.

SpawnedHandle(TaskId)

Resume after a handle-bearing spawn with the child’s task id.
