Enum mmtk::plan::BarrierSelector

pub enum BarrierSelector {
    NoBarrier,
    ObjectBarrier,
}

BarrierSelector describes which barrier to use.

This is used as an indicator for each plan to enable the correct barrier. For example, immix can use this selector to enable different barriers for analysis.

VM bindings may also use this to enable the correct fast-path, if the fast-path is implemented in the binding.

Variants

NoBarrier

No barrier is used.

ObjectBarrier

Object remembering barrier is used.

Implementations

impl BarrierSelector

pub const fn equals(&self, other: BarrierSelector) -> bool

A const function to check if two barrier selectors are the same.

Trait Implementations

impl Clone for BarrierSelector

fn clone(&self) -> BarrierSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BarrierSelector

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

Formats the value using the given formatter.

impl PartialEq for BarrierSelector

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

This method tests for self and other values to be equal, and is used by ==.

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

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