fn check_live_drop(&self, span: Span)

Methods from Deref<Target = ConstCx<'mir, 'tcx>>

pub fn def_id(&self) -> LocalDefId

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.

pub fn is_const_stable_const_fn(&self) -> bool

pub fn fn_sig(&self) -> Option<&'tcx FnSig<'tcx>>

Returns the function signature of the item being const-checked if it is a fn or const fn.

Trait Implementations

impl<'mir, 'tcx> Deref for CheckLiveDrops<'mir, 'tcx>

type Target = ConstCx<'mir, 'tcx>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

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.
