Implementations

impl OnError

pub fn custom(f: impl FnOnce(&Error) -> OnError + 'static + Send + Sync) -> Self

Creates an error strategy based on the given closure. Convenience wrapper over OnError::Custom that boxes the closure for you.

pub fn ignore_with(f: impl FnOnce(&Error) + 'static + Send + Sync) -> Self

Creates an error strategy that runs the given closure and ignores the error.

pub fn propagate_with(f: impl FnOnce(&Error) + 'static + Send + Sync) -> Self

Creates an error strategy that runs the given closure and propagates it to the nursery.
