Variants

NoMatch(NoMatchData<'tcx>)

Did not find an applicable method, but we did find various near-misses that may work.

Ambiguity(Vec<CandidateSource>)

Multiple methods might apply.

PrivateMatch(DefKind, DefId, Vec<DefId>)

Found an applicable method, but it is not visible. The third argument contains a list of not-in-scope traits which may work.

IllegalSizedBound

Found a Self: Sized bound where Self is a trait object.

Fields

candidates: Vec<DefId>

needs_mut: bool

bound_span: Span

self_expr: &'tcx Expr<'tcx>

BadReturnType

Found a match, but the return type is wrong

ErrorReported(ErrorGuaranteed)

Error has already been emitted, no need to emit another one.

Trait Implementations

impl<'tcx> Debug for MethodError<'tcx>

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

Formats the value using the given formatter.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
