CancellationTokenRegistration

Struct CancellationTokenRegistration 

Source 
pub struct CancellationTokenRegistration { /* private fields */ }
Expand description

Represents a registered callback on a CancellationToken.

When this object is dropped before the token is cancelled, the callback is automatically removed. If the token is already cancelled, Drop does nothing.

This ensures that callbacks are only called once and resources are cleaned up.

Single-threaded only. Not safe to use concurrently.
