PoppedHandle

kernel_api::syscall::handle

Struct PoppedHandle 

Source 
pub struct PoppedHandle(/* private fields */);
Available on crate feature full only.
Expand description

A wrapper around a Handle that has been removed from a HandleMap but not yet dropped.

This exists to allow a faster path when moving a handle between two maps, by delaying any refcount adjustments on a popped handle until the wrapper is dropped.
