Implementations§

Source§

impl<R> FastCasSuccess<R>

Source

pub const fn previous(&self) -> usize

Returns the state observed before successful completion.

§Returns

The state code read by the successful attempt.

Source

pub const fn current(&self) -> usize

Returns the state after completion.

§Returns

The installed state for updates, or previous for finishes.

Source

pub const fn output(&self) -> &R

Returns a shared reference to the business output.

§Returns

The output produced by the operation.

Source

pub fn into_output(self) -> R

Consumes this result and returns the business output.

§Returns

The output produced by the operation.

Source

pub const fn attempts(&self) -> u32

Returns the number of attempts consumed.

§Returns

Number of attempts executed by the operation.

Source

pub const fn is_updated(&self) -> bool

Tests whether this success came from an update decision.

§Returns

true when the operation successfully executed an update decision, even if the installed state equals the previously observed state.

Source

pub const fn is_finished(&self) -> bool

Tests whether this success came from a finish decision.

§Returns

true when the operation completed through a finish decision.
