Implementations

impl<L, T> ExecutorLockBuilder<L, T>

where L: Lock<T>,

pub fn log_unmet_condition( self, level: Level, message: impl Into<String>, ) -> Self

Configures logging when the double-checked condition is not met.

pub fn log_prepare_failure( self, level: Level, message_prefix: impl Into<String>, ) -> Self

Configures logging when the prepare action fails.

pub fn log_prepare_commit_failure( self, level: Level, message_prefix: impl Into<String>, ) -> Self

Configures logging when the prepare commit action fails.

pub fn log_prepare_rollback_failure( self, level: Level, message_prefix: impl Into<String>, ) -> Self

Configures logging when the prepare rollback action fails.

pub fn when<Tst>(self, tester: Tst) -> ExecutorReadyBuilder<L, T>

where Tst: Tester + Send + Sync + 'static,

Configures the required double-checked condition.

The tester is executed outside and inside the lock. State read by the outside check must be safe to access without this executor’s lock.

Parameters

• tester - The reusable condition tester.

Returns

The builder state that can configure prepare callbacks and build the executor.
