Implementations

source

impl<'a, 'tcx> Trace<'a, 'tcx>

source

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

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

source

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

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

source

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

source

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

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.
