Enum MirHeapOwnership

pub enum MirHeapOwnership {
    None,
    Owned,
    OwnedShallow,
    BorrowedView,
}

Heap ownership policy carried by one MIR local.

Variants

None

Local does not participate in runtime heap retain/release operations.

Owned

Local owns one runtime heap allocation that must be released.

OwnedShallow

Local owns one runtime container whose nested payload is borrowed/shared.

BorrowedView

Local denotes a borrowed slice view and must not run retain/release.

Implementations

impl MirHeapOwnership

pub fn uses_heap_ops(self) -> bool

Return whether this ownership class requires runtime retain/release operations.

Trait Implementations

impl Clone for MirHeapOwnership

fn clone(&self) -> MirHeapOwnership

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MirHeapOwnership

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for MirHeapOwnership

fn eq(&self, other: &MirHeapOwnership) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
