Trait Implementations

impl<'tcx> Clone for TypeError<'tcx>

fn clone(&self) -> TypeError<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for TypeError<'tcx>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'tcx> Display for TypeError<'tcx>

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.

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a, 'tcx> Lift<'tcx> for TypeError<'a>

type Lifted = TypeError<'tcx>

🔬 This is a nightly-only experimental API. (rustc_private)

fn lift_to_tcx<'b, 'gcx>(&self,
                         tcx: TyCtxt<'b, 'gcx, 'tcx>)
                         -> Option<Self::Lifted>
