Enums

VarianceDiagInfo

Extra information about why we ended up with a particular variance. This is only used to add more information to error messages, and has no effect on soundness. While choosing the ‘wrong’ VarianceDiagInfo may lead to confusing notes in error messages, it will never cause a miscompilation or unsoundness.

Functions

relate_args_invariantly

relate_args_with_variances

structurally_relate_consts

Relates a and b structurally, calling the relation for all nested values. Any semantic equality, e.g. of alias consts, and inference variables have to be handled by the caller.

structurally_relate_tys

Relates a and b structurally, calling the relation for all nested values. Any semantic equality, e.g. of projections, and inference variables have to be handled by the caller.
