Extension methods for std::result::Result.

Required Methods

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

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

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

Maps a Result<T, E> to Result<T, String> by converting the Err result into a string using the “alternate” formatting.
