Unstable (rustc_private)

constant evaluation on the HIR and code to validate patterns/matches

Note

This API is completely unstable and subject to change.

check_match	[Unstable]
diagnostics	[Unstable]

[Unstable]

ErrKind	[Unstable]
EvalHint	[Unstable] Hint to determine how to evaluate constant expressions which might not be type-checked.

compare_const_vals	[Unstable]
compare_lit_exprs	[Unstable]
const_expr_to_pat	[Unstable]
eval_const_expr	[Unstable]
eval_const_expr_partial	[Unstable] Evaluate a constant expression in a context where the expression isn't guaranteed to be evaluatable. `ty_hint` is usually ExprTypeChecked, but a few places need to evaluate constants during type-checking, like computing the length of an array. (See also the FIXME above EvalHint.)
eval_repeat_count	[Unstable] Returns the repeat count for a repeating vector expression.
lookup_const_by_id	[Unstable] `def_id` is the id of the constant. `substs` is the monomorphized substitutions for the expression.
lookup_const_fn_by_id	[Unstable]
