Struct Handle

pub struct Handle<T> { /* private fields */ }

A reference to an ID referring to an item in the compiler instance.

The usage of Handle<T> ensures that item IDs can not be forged from a different compiler instance or from a u32.

Implementations

impl<T: Id> Handle<T>

pub fn id(&self) -> u32

Return the u32 part of the Id.

Note that Handle<T> can not implement Id for safety reasons. Getting an impl Id out of a Handle<T> requires using Compiler::yield_id.

Trait Implementations

impl<T: Clone> Clone for Handle<T>

fn clone(&self) -> Handle<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Handle<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, 'b> From<&'a BuiltinResource<'b>> for Handle<VariableId>

fn from(value: &'a BuiltinResource<'b>) -> Self

Converts to this type from the input type.

impl<'a, 'b> From<&'a Resource<'b>> for Handle<VariableId>

fn from(value: &'a Resource<'b>) -> Self

Converts to this type from the input type.

impl From<BuiltinResource<'_>> for Handle<VariableId>

fn from(value: BuiltinResource<'_>) -> Self

Converts to this type from the input type.

impl From<Handle<ConstantId>> for DecorationValue<'_>

fn from(value: Handle<ConstantId>) -> Self

Converts to this type from the input type.

impl From<Resource<'_>> for Handle<VariableId>

fn from(value: Resource<'_>) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Handle<T>

fn eq(&self, other: &Handle<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
