Trait std::error::Error

pub trait Error: Debug + Display {
    fn description(&self) -> &str;

    fn cause(&self) -> Option<&Error> { ... }
}

Base functionality for all errors in Rust.

Required Methods

fn description(&self) -> &str

A short description of the error.

The description should not contain newlines or sentence-ending punctuation, to facilitate embedding in larger user-facing strings.

Provided Methods

fn cause(&self) -> Option<&Error>

The lower-level cause of this error, if any.
