Fields

has_mut_interior: Option<ResultsCursor<'mir, 'tcx, FlowSensitiveAnalysis<'mir, 'mir, 'tcx, HasMutInterior>>>

needs_drop: Option<ResultsCursor<'mir, 'tcx, FlowSensitiveAnalysis<'mir, 'mir, 'tcx, NeedsDrop>>>

Implementations

impl<'mir, 'tcx> Qualifs<'mir, 'tcx>

pub fn indirectly_mutable(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

pub fn needs_drop(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

Returns true if local is NeedsDrop at the given Location.

Only updates the cursor if absolutely necessary

pub fn has_mut_interior(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    local: Local,
    location: Location
) -> bool

Returns true if local is HasMutInterior at the given Location.

Only updates the cursor if absolutely necessary.

fn in_return_place(
    &mut self,
    ccx: &'mir ConstCx<'mir, 'tcx>,
    error_occured: Option<ErrorReported>
) -> ConstQualifs

Trait Implementations

impl<'mir, 'tcx> Default for Qualifs<'mir, 'tcx>

fn default() -> Qualifs<'mir, 'tcx>

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
