Struct ReservedAllocators

source 
pub(crate) struct ReservedAllocators {
    pub n_bump_pointer: u8,
    pub n_large_object: u8,
    pub n_malloc: u8,
    pub n_immix: u8,
    pub n_mark_compact: u8,
    pub n_free_list: u8,
}
Expand description

This is used for plans to indicate the number of allocators reserved for the plan. This is used as a parameter for creating allocator/space mapping. A plan is required to reserve the first few allocators. For example, if n_bump_pointer is 1, it means the first bump pointer allocator will be reserved for the plan (and the plan should initialize its mapping itself), and the spaces in common/base plan will use the following bump pointer allocators.

Implementations§

source§

impl ReservedAllocators

source

pub const DEFAULT: Self = _

source

fn validate(&self)

check if the number of each allocator is okay. Panics if any allocator exceeds the max number.

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

§

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

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

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

§

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

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

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

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