Implementations§

source§

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

source

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

Makes a <: b.

source

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

Makes a :> b.

source

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

Makes a == b.

source

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

Equates a and b while structurally relating aliases. This should only be used inside of the next generation trait solver when relating rigid aliases.

source

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

source

pub fn glb<T>( self, define_opaque_types: DefineOpaqueTypes, 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.
