Struct StaleOperation 

Source 
pub struct StaleOperation<O> { /* private fields */ }
Expand description

Operation metadata recovered only after its queue epoch is stale.

Implementations§

Source§

impl<O> StaleOperation<O>

Source

pub const fn request_id(&self) -> u64

Request identifier from the invalidated queue epoch.

Source

pub const fn epoch(&self) -> QueueEpoch

Invalidated queue epoch.

Source

pub const fn operation(&self) -> &O

Borrow the invalidated operation metadata.

Source

pub fn into_operation(self) -> O

Recover operation metadata for cleanup or inspection.

Typed handles from this operation remain stale and cannot be republished in the new epoch.
