Struct AtomicCancel 

pub struct AtomicCancel { /* private fields */ }

Shared atomic cancellation flag.

Safe to share across threads via Arc or bare references. Setting the flag does not interrupt a thread blocked in kernel I/O; pair with CancellableRead for poll-between-reads, and kill_child_if_cancelled (or closing the HTTP body) for preemptive wake-up.

Implementations

impl AtomicCancel

pub const fn new() -> Self

Create a flag that is not yet cancelled.

pub fn cancel(&self)

Request cancellation. Subsequent polls return true. Idempotent.

pub fn clear(&self)

Clear the flag so a subsequent operation can reuse this source.

pub fn is_cancelled(&self) -> bool

Current flag value.
