sourceimpl Error
impl Error
sourcepub fn use_stderr(&self) -> bool
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

and exits with a status of 1
. Otherwise, stdout
is used
with a status of 0
