Implementations

impl Error

pub fn use_stderr(&self) -> bool

Should the message be written to stdout or not

pub fn exit(&self) -> !

Prints the error message and exits. If Error::use_stderr evaluates to true, the message will be written to stderr and exits with a status of 1. Otherwise, stdout is used with a status of 0.

pub fn with_description(description: &str, kind: ErrorKind) -> Error

Create an error with a custom description.

This can be used in combination with Error::exit to exit your program with a custom error message.
