NeedsNonConstDrop

rustc_const_eval::check_consts::qualifs

Struct NeedsNonConstDrop 

Source 
pub struct NeedsNonConstDrop;
Expand description

Constant containing an ADT that implements non-const Drop. This must be ruled out because we cannot run Drop during compile-time.

Trait Implementations§

Source§

impl Qualif for NeedsNonConstDrop

Source§

const ANALYSIS_NAME: &'static str = "flow_needs_nonconst_drop"

The name of the file used to debug the dataflow analysis that computes this qualif.
Source§

const IS_CLEARED_ON_MOVE: bool = true

Whether this Qualif is cleared when a local is moved from.
Source§

const ALLOW_PROMOTED: bool = true

Whether this Qualif might be evaluated after the promotion and can encounter a promoted.
Source§

fn in_qualifs(qualifs: &ConstQualifs) -> bool

Extracts the field of ConstQualifs that corresponds to this Qualif.
Source§

fn in_any_value_of_ty<'tcx>(cx: &ConstCx<'_, 'tcx>, ty: Ty<'tcx>) -> bool

Source§

fn is_structural_in_adt_value<'tcx>( cx: &ConstCx<'_, 'tcx>, adt: AdtDef<'tcx>, ) -> bool

Returns true if the Qualif is structural in an ADT’s fields, i.e. if we may recurse into an operand value to determine whether it has this Qualif. Read more
