Trait ErrorOps 

pub trait ErrorOps<E>: WithError<E> {
    // Required methods
    fn recover<F>(self, recovery: F) -> Self
       where F: FnOnce(E) -> Self,
             Self: Sized;
    fn bimap_result<B, F, SuccessF, ErrorF>(
        self,
        success_f: SuccessF,
        error_f: ErrorF,
    ) -> Result<B, F>
       where SuccessF: FnOnce(Self::Success) -> B,
             ErrorF: FnOnce(E) -> F,
             Self: Sized;
}

Operations for error recovery and bidirectional mapping.

Required Methods

fn recover<F>(self, recovery: F) -> Self

where F: FnOnce(E) -> Self, Self: Sized,

Attempts to recover from an error using the provided recovery function.

fn bimap_result<B, F, SuccessF, ErrorF>( self, success_f: SuccessF, error_f: ErrorF, ) -> Result<B, F>

where SuccessF: FnOnce(Self::Success) -> B, ErrorF: FnOnce(E) -> F, Self: Sized,

Maps both success and error cases simultaneously.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
