[−][src]Macro unwrap_return::unwrap_do
Unwraps in the Some
case; does something in the None
case.
Usually you want unwrap_or_else
from the standard library. Use this for cases where
you need to do something simple before returning or breaking, or you want to return a value.
unwrap_do!(expression, do)
is shorthand for
match expression { Some(ret) => ret, None => { do } }
