Struct rustc_const_eval::transform::promote_consts::Validator
source · struct Validator<'a, 'tcx> {
ccx: &'a ConstCx<'a, 'tcx>,
temps: &'a mut IndexSlice<Local, TempState>,
}
Expand description
Checks whether locals that appear in a promotion context (Candidate
) are actually promotable.
This wraps an Item
, and has access to all fields of that Item
via Deref
coercion.

Methods from Deref<Target = ConstCx<'a, 'tcx>>§
pub fn def_id(&self) -> LocalDefId
sourcepub fn const_kind(&self) -> ConstContext
pub fn const_kind(&self) -> ConstContext
Returns the kind of const context this Item
represents (const
, static
, etc.).
Panics if this Item
is not const.

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.
