[src]

[src]
impl<'tcx> Display for TypeError<'tcx>
[src]
Explains the source of a type err in a short, human readable way. This is meant to be placed
in parentheses after some larger message. You should also invoke note_and_explain_type_err()
afterwards to present additional details, particularly when it comes to lifetime-related
errors.
