Struct cart_tmp_nga::Arena

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

An arena holding some kind of component (e.g., type, constant, instruction, etc.) that can be referenced.

Implementations

impl<T> Arena<T>

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

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

pub fn append(&mut self, value: T) -> Handle<T>

Adds a new value to the arena, returning a typed handle.

The value is not linked to any SPIR-V module.

pub fn fetch_or_append(&mut self, value: T) -> Handle<T> where
    T: PartialEq, 

Adds a value with a check for uniqueness: returns a handle pointing to an existing element if its value matches the given one, or adds a new element otherwise.

impl<T> Default for Arena<T>

fn default() -> Self

Returns the "default value" for a type.

impl<T> Index<Handle<T>> for Arena<T>

type Output = T

The returned type after indexing.

fn index(&self, handle: Handle<T>) -> &T

Performs the indexing (container[index]) operation.
