Struct Instance 

pub struct Instance { /* private fields */ }

the browser’s WebGPU; adapter and device come asynchronously (prepare)

Implementations

impl Instance

pub fn new() -> Result<Instance>

the browser’s WebGPU, adapter and device asked for (prepare says when they are there)

pub fn with(_desc: &InstanceDesc<'_>) -> Result<Instance>

(app_name and validate mean nothing here: the browser validates every call)

pub fn prepare(&self) -> Result<bool>

have the browser’s adapter and device arrived? Never waits; a worker gets them by returning to the browser’s event loop. (true at once on the other targets.)

pub fn validating(&self) -> bool

pub fn adapters(&self) -> Result<Vec<Adapter>>

the one adapter the browser offers

pub fn adapter(&self) -> Result<Adapter>

pub fn adapters_low_power( &self, _display: Option<(u32, u32)>, ) -> Result<Vec<Adapter>>

the adapter for showing windows: not a software one, which is no gain over the CPU path

Trait Implementations

impl Clone for Instance

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
