[−][src]Struct rustc_infer::infer::at::Trace

pub struct Trace<'a, 'tcx> {
    at: At<'a, 'tcx>,
    a_is_expected: bool,
    trace: TypeTrace<'tcx>,
}

Fields

at: At<'a, 'tcx>a_is_expected: booltrace: TypeTrace<'tcx>

Implementations

impl<'a, 'tcx> Trace<'a, 'tcx>[src]

pub fn sub<T>(self, a: T, b: T) -> InferResult<'tcx, ()> where
    T: Relate<'tcx>, [src]

Makes a <: b where a may or may not be expected (if a_is_expected is true, then a is expected).

pub fn eq<T>(self, a: T, b: T) -> InferResult<'tcx, ()> where
    T: Relate<'tcx>, [src]

Makes a == b; the expectation is set by the call to trace().

pub fn lub<T>(self, a: T, b: T) -> InferResult<'tcx, T> where
    T: Relate<'tcx>, [src]

pub fn glb<T>(self, a: T, b: T) -> InferResult<'tcx, T> where
    T: Relate<'tcx>, [src]
