Struct TaskCall 

pub struct TaskCall { /* private fields */ }

One import-task call in flight.

Implementations

impl TaskCall

pub fn new(call: impl FnOnce() -> i32 + 'static) -> Option<TaskCall>

Prepares call (the C import, returning its int) to run on its own stack at the first Self::poll. None when no stack can be mapped.

pub fn poll(&mut self) -> CallPoll

Runs the call until it finishes or blocks in an export task.

pub fn disable(&mut self)

Marks the call disabled (35.9): the blocked export call returns EXPORT_CALL_DISABLED on the next Self::poll, and every export the C code calls after that returns it at once.

pub fn import_name(&self) -> String

The SV name of the import task this call runs (set while it is inside the call, empty for a call outside any import task).

pub fn is_finished(&self) -> bool

Whether the C function has returned.
