Struct ParseControl 

pub struct ParseControl { /* private fields */ }

A clonable cancellation handle for a parse operation.

Existing parsing entry points do not require a control. Callers that need cancellation can create one, pass a reference to the controlled entry point, and call ParseControl::cancel from another thread.

Clones share cancellation state. A canceled control remains canceled, so create a fresh control for each independent parse job.

Implementations

impl ParseControl

pub fn new() -> Self

Create a control in the running state.

pub fn cancel(&self)

Request cooperative cancellation.

This operation is thread-safe, inexpensive, and idempotent.

pub fn is_cancelled(&self) -> bool

Return whether cancellation has been requested.
