Extension methods for std::result::Result.

Required Methods

fn err_into<E2>(self) -> Result<T, E2>

where E: Into<E2>,

Applies Into::into to a contained Err value, leaving an Ok value untouched.

fn err_to_string_with_causes(&self) -> Option<String>

where E: Error,

Formats an Err value as a detailed error message, preserving any context information.

This is equivalent to format!("{}", err.display_with_causes()), except that it’s easier to type.

fn map_err_to_string_with_causes(self) -> Result<T, String>

where E: Error,

Maps a Result<T, E> to Result<T, String> by converting the Err result into a string, along with the chain of source errors, if any.

fn infallible_unwrap(self) -> T

where E: Into<Infallible>,

Safely unwraps a Result<T, Infallible>, where Infallible is a type that represents when an error cannot occur.

Object Safety

This trait is not object safe.
