Implementations§

source§

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

source

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

Makes a <: b.

source

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

Makes a :> b.

source

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

Makes a == b.

source

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

source

pub fn glb<T>( self, define_opaque_types: DefineOpaqueTypes, a: T, b: T ) -> Result<InferOk<'tcx, T>, TypeError<'tcx>>
