Struct CopyConfig

source 
pub struct CopyConfig<VM: VMBinding> {
    pub(crate) copy_mapping: EnumMap<CopySemantics, CopySelector>,
    pub(crate) space_mapping: Vec<(CopySelector, &'static dyn Space<VM>)>,
    pub(crate) constraints: &'static PlanConstraints,
}
Expand description

A configuration for GCWorkerCopyContext. Similar to a MutatorConfig, We expect each copying plan to provide a CopyConfig.

Fields§

§copy_mapping: EnumMap<CopySemantics, CopySelector>

Mapping CopySemantics to the actual copying allocators (CopySelector)

§space_mapping: Vec<(CopySelector, &'static dyn Space<VM>)>

Mapping copying allocators with space

§constraints: &'static PlanConstraints

A reference to the plan constraints. GCWorkerCopyContext may have plan-specific behaviors dependson the plan constraints.

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

§

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
