Enum PointerKind

pub enum PointerKind {
    SharedRef {
        frozen: bool,
    },
    MutableRef {
        unpin: bool,
    },
    Box {

Variants

SharedRef

Shared reference. frozen indicates the absence of any UnsafeCell.

Fields

frozen: bool

MutableRef

Mutable reference. unpin indicates the absence of any pinned data.

Fields

unpin: bool

Box

Box. unpin indicates the absence of any pinned data. global indicates whether this box uses the global allocator or a custom one.

Fields

unpin: bool

global: bool

Trait Implementations

impl Clone for PointerKind

fn clone(&self) -> PointerKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointerKind

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

Formats the value using the given formatter.

impl PartialEq for PointerKind

fn eq(&self, other: &PointerKind) -> 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.

impl Copy for PointerKind

impl Eq for PointerKind

impl StructuralPartialEq for PointerKind

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.
