Struct rustc_infer::infer::TypeTrace

pub struct TypeTrace<'tcx> {
    pub cause: ObligationCause<'tcx>,
    pub values: ValuePairs<'tcx>,
}

The trace designates the path through inference that we took to encounter an error or subtyping constraint.

See the error_reporting module for more details.

Fields

cause: ObligationCause<'tcx>

values: ValuePairs<'tcx>

Implementations

impl<'tcx> TypeTrace<'tcx>

Trait Implementations

impl<'tcx> Clone for TypeTrace<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for TypeTrace<'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.
