Struct CancellationToken 

pub struct CancellationToken { /* private fields */ }

A cancellation token for tracking request cancellation.

This is a simple wrapper around an atomic boolean that can be shared across threads and checked for cancellation.

Implementations

impl CancellationToken

pub fn new() -> Self

Create a new cancellation token.

pub fn is_cancelled(&self) -> bool

Check if cancellation has been requested.

pub fn cancel(&self)

Request cancellation.

pub fn cancelled(&self) -> CancelledFuture

Wait for cancellation.

Returns a future that completes when cancellation is requested.

Note: In a production implementation, this would integrate with the runtime’s notification system. This simple implementation polls the atomic flag.
