pub struct ErrorGuaranteed(pub(crate) ());
Expand description
Useful type to use with Result<>
indicate that an error has already
been reported to the user, so no need to continue checking.
The ()
field is necessary: it is non-pub
, which means values of this
type cannot be constructed outside of this crate.
