Struct rafx_base::slab::RawSlab

pub struct RawSlab<T> { /* fields omitted */ }

A very simple, minimalist slab structure. Consider using one of the other slabs instead as they are less error prone for many use-cases.

Implementations

impl<T> RawSlab<T>

pub fn new() -> Self

Create an empty RawSlab

pub fn with_capacity(capacity: SlabIndexT) -> Self

Create an empty but presized RawSlab

pub fn allocate(&mut self, value: T) -> RawSlabKey<T>

Allocate a slot within the raw slab.

Allocation can cause vectors to be resized. Use with_capacity to avoid this.

pub fn allocate_with_key<F: FnMut(RawSlabKey<T>) -> T>(
    &mut self,
    f: F
) -> RawSlabKey<T>

pub fn free(&mut self, slab_key: RawSlabKey<T>)

Free an element in the raw slab. It is fatal to free an element that doesn’t exist.

pub fn exists(&self, slab_key: RawSlabKey<T>) -> bool

Check if an element exists

pub fn get(&self, slab_key: RawSlabKey<T>) -> Option<&T>

Try to get the given element

pub fn get_mut(&mut self, slab_key: RawSlabKey<T>) -> Option<&mut T>

Try to get the given element

pub fn iter(&self) -> impl Iterator<Item = (RawSlabKey<T>, &T)>

Iterate all values

pub fn iter_mut(&mut self) -> impl Iterator<Item = (RawSlabKey<T>, &mut T)>

Iterate all values

pub fn allocated_count(&self) -> usize

Return count of allocated Ts

pub fn storage_size(&self) -> usize

Trait Implementations

impl<T> Default for RawSlab<T>

fn default() -> Self

Returns the “default value” for a type.
