pub enum WeakMapTraceAction {

    TraceKeysAndValues = 3,
}

Variants

Skip = 0

Do not trace into weak map keys or values during traversal. Users must handle weak maps manually.

Expand = 1

Do true ephemeron marking with a weak key lookup marking phase. This is the default for GCMarker.

TraceValues = 2

Trace through to all values, irrespective of whether the keys are live or not. Used for non-marking tracers.

TraceKeysAndValues = 3

Trace through to all keys and values, irrespective of whether the keys are live or not. Used for non-marking tracers.

Trait Implementations

impl Clone for WeakMapTraceAction

fn clone(&self) -> WeakMapTraceAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WeakMapTraceAction

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

Formats the value using the given formatter.

impl Hash for WeakMapTraceAction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WeakMapTraceAction

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