Enum RequestAdapterError 

#[non_exhaustive]
pub enum RequestAdapterError {
    NotFound { /* private fields */ },
    EnvNotSet,
}

Available on crate feature unstable-wgpu-26 only.

Error when Instance::request_adapter() fails.

This type is not part of the WebGPU standard, where requestAdapter() would simply return null.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound

No adapter available via the instance’s backends matched the request’s adapter criteria.

EnvNotSet

Attempted to obtain adapter specified by environment variable, but the environment variable was not set.

Trait Implementations

impl Clone for RequestAdapterError

fn clone(&self) -> RequestAdapterError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestAdapterError

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

Formats the value using the given formatter.

impl Display for RequestAdapterError

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

Formats the value using the given formatter.

impl Error for RequestAdapterError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RequestAdapterError

fn eq(&self, other: &RequestAdapterError) -> 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.
