Trait ResultErrorContext

pub(crate) trait ResultErrorContext {
    // Required method
    fn err_context<C: Display, F: FnOnce() -> C>(self, context: F) -> Self;
}

Give results context in case of error.

Lifts the ErrorContext trait to Result types.

Required Methods

fn err_context<C: Display, F: FnOnce() -> C>(self, context: F) -> Self

Give context if self is an error.

If self is an error, prepend the given 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.
