Implementations
impl Error
[src]
pub fn use_stderr(&self) -> bool
[src]
Should the message be written to stdout
or not
pub fn exit(&self) -> !

Prints the error to stderr
and exits with a status of 1
pub fn with_description(description: &str, kind: ErrorKind) -> Self
[src]
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.
