Implementations§

Source§

impl<L, T> DoubleCheckedLockBuilder<L, T>
where L: Lock<T>,

Source

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

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

§Parameters
  • level - Log level used for unmet-condition messages.
  • message - Full log message emitted when the condition is not met.
§Returns

This builder with unmet-condition logging configured.

Source

pub fn disable_unmet_condition_logging(self) -> Self

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

§Returns

This builder with unmet-condition logging disabled.

Source

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

Configures logging when the prepare action fails.

§Parameters
  • level - Log level used for prepare failure messages.
  • message_prefix - Prefix placed before the prepare failure text.
§Returns

This builder with prepare failure logging configured.

Source

pub fn disable_prepare_failure_logging(self) -> Self

Disables logging when the prepare action fails.

§Returns

This builder with prepare failure logging disabled.

Source

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

Configures logging when the prepare commit action fails.

§Parameters
  • level - Log level used for prepare-commit failure messages.
  • message_prefix - Prefix placed before the prepare-commit failure text.
§Returns

This builder with prepare-commit failure logging configured.

Source

pub fn disable_prepare_commit_failure_logging(self) -> Self

Disables logging when the prepare commit action fails.

§Returns

This builder with prepare-commit failure logging disabled.

Source

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

Configures logging when the prepare rollback action fails.

§Parameters
  • level - Log level used for prepare-rollback failure messages.
  • message_prefix - Prefix placed before the prepare-rollback failure text.
§Returns

This builder with prepare-rollback failure logging configured.

Source

pub fn disable_prepare_rollback_failure_logging(self) -> Self

Disables logging when the prepare rollback action fails.

§Returns

This builder with prepare-rollback failure logging disabled.

Source

pub fn catch_panics(self) -> Self

Enables panic capture for tester, prepare callbacks, and task execution.

§Returns

This builder with panic capture enabled.

Source

pub fn with_panic_capture(self, catch_panics: bool) -> Self

Derives a builder with panic capture enabled or disabled for tester, prepare callbacks, and task execution.

§Parameters
  • catch_panics - true to capture panics as execution errors, or false to let panics unwind.
§Returns

A reconfigured builder with the updated panic-capture setting.

Source

pub fn disable_catch_panics(self) -> Self

Disables panic capture for tester, prepare callbacks, and task execution.

§Returns

This builder with panic capture disabled.

Source

pub fn when<Tst>(self, tester: Tst) -> DoubleCheckedLockReadyBuilder<L, T>
where Tst: Tester + Send + Sync + 'static,

Sets the required double-checked condition.

§Parameters
  • tester - Condition tester executed before and after acquiring the lock.
§Returns

A ready builder that can configure prepare callbacks or run the task.
