Struct naga::back::spv::CachedExpressions

struct CachedExpressions {
    ids: HandleVec<Expression, Word>,
}

A map from evaluated Expressions to their SPIR-V ids.

When we emit code to evaluate a given Expression, we record the SPIR-V id of its value here, under its Handle<Expression> index.

A CachedExpressions value can be indexed by a Handle<Expression> value.

Fields

ids: HandleVec<Expression, Word>

Implementations

impl CachedExpressions

fn reset(&mut self, length: usize)

Trait Implementations

impl Default for CachedExpressions

fn default() -> CachedExpressions

Returns the “default value” for a type.

impl Index<Handle<Expression>> for CachedExpressions

type Output = u32

The returned type after indexing.

fn index(&self, h: Handle<Expression>) -> &Word

Performs the indexing (container[index]) operation.

impl IndexMut<Handle<Expression>> for CachedExpressions

fn index_mut(&mut self, h: Handle<Expression>) -> &mut Word

Performs the mutable indexing (container[index]) operation.

impl Recyclable for CachedExpressions

fn recycle(self) -> Self

Clear self, retaining its current memory allocations.
