Struct DropGuardRef 

Source 
pub struct DropGuardRef<'a> { /* private fields */ }
Expand description

A wrapper for cancellation token which automatically cancels it on drop. It is created using drop_guard_ref method on the CancellationToken.

This is a borrowed version of DropGuard.

Implementations§

Source§

impl<'a> DropGuardRef<'a>

Source

pub fn disarm(self) -> &'a CancellationToken

Returns stored cancellation token and removes this drop guard instance (i.e. it will no longer cancel token). Other guards for this token are not affected.
