Expand description

A trait providing conversion shortcuts for creating Error instances.

Required Methods§

Source

fn ok_or_error<C, F>(self, kind: ErrorKind, f: F) -> Result<T, Error>
where C: ToString, F: FnOnce() -> C,

Unwrap self into an Ok or an Error of the given kind.

Provided Methods§

Source

fn ok_or_invalid_data<C, F>(self, f: F) -> Result<T, Error>
where C: ToString, F: FnOnce() -> C,

Unwrap self into an Ok or an Error of the ErrorKind::InvalidData kind.

Source

fn ok_or_invalid_input<C, F>(self, f: F) -> Result<T, Error>
where C: ToString, F: FnOnce() -> C,

Unwrap self into an Ok or an Error of the ErrorKind::InvalidInput kind.

Source

fn ok_or_not_found<C, F>(self, f: F) -> Result<T, Error>
where C: ToString, F: FnOnce() -> C,

Unwrap self into an Ok or an Error of the ErrorKind::NotFound kind.

Source

fn ok_or_unexpected_eof<C, F>(self, f: F) -> Result<T, Error>
where C: ToString, F: FnOnce() -> C,

Unwrap self into an Ok or an Error of the ErrorKind::UnexpectedEof kind.

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.
