Struct Handle

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

A strongly typed reference to an arena item.

A Handle value can be used as an index into an Arena or UniqueArena.

Implementations

impl<T> Handle<T>

pub const fn index(self) -> usize

Returns the index of this handle.

pub fn write_prefixed( &self, formatter: &mut Formatter<'_>, prefix: &'static str, ) -> Result

Write this handle’s index to formatter, preceded by prefix.

impl Handle<Type>

pub fn to_wgsl(self, gctx: &GlobalCtx<'_>) -> String

Formats the type as it is written in wgsl.

For example vec3<f32>.
