A trait for wrapping an existing result error with a additional context.

Required Methods

fn kind(self, kind: K) -> UniResult<T, K>

Wraps the existing result error with the provided kind.

fn context(self, context: impl Into<Cow<'static, str>>) -> UniResult<T, K>

where K: Default,

Wraps the existing result error with the provided context.

fn kind_context( self, kind: K, context: impl Into<Cow<'static, str>>, ) -> UniResult<T, K>

Wraps the existing result error with the provided kind and context.

fn wrap(self) -> UniResult<T, K>

where K: Default,

Wraps the existing result error with no additional context.

Provided Methods

fn kind_fn<F>(self, kind: F) -> UniResult<T, K>

where F: FnOnce(&Self) -> K, Self: Sized,

Wraps the existing result error with the provided kind.

fn context_fn<F, S>(self, context: F) -> UniResult<T, K>

where F: FnOnce(&Self) -> S, S: Into<Cow<'static, str>>, K: Default, Self: Sized,

Wraps the existing result error with the provided context.

fn kind_context_fn<F, F2, S>(self, kind: F, context: F2) -> UniResult<T, K>

where F: FnOnce(&Self) -> K, F2: FnOnce(&Self) -> S, S: Into<Cow<'static, str>>, Self: Sized,

Wraps the existing result error with the provided kind and context.

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.
