Enum OnAllocationFail

#[repr(u8)]
pub enum OnAllocationFail {
    RequestGC = 0,
    ReturnFailure = 1,
    OverCommit = 2,
}

Behavior when an allocation fails, and a GC is expected.

Variants

RequestGC = 0

Request the GC. This is the default behavior.

ReturnFailure = 1

Instead of requesting GC, the allocation request returns with a failure value.

OverCommit = 2

Instead of requesting GC, the allocation request simply overcommits the memory, and return a valid result at its best efforts.

Trait Implementations

impl Clone for OnAllocationFail

fn clone(&self) -> OnAllocationFail

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OnAllocationFail

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

Formats the value using the given formatter.

impl Default for OnAllocationFail

fn default() -> OnAllocationFail

Returns the “default value” for a type.

impl PartialEq for OnAllocationFail

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