Struct DeviceRequirementsError 

pub struct DeviceRequirementsError {
    pub adapter: String,
    pub backend: Backend,
    pub missing_limits: Vec<MissingLimit>,
    pub missing_features: Features,
}

The adapter can’t provide the limits or features the game asked for in GraphicsConfig. Returned (inside the anyhow::Error) by Graphics::new; downcast_ref it to tell it apart from other init failures.

WebGL2 (the web fallback when the browser has no WebGPU) has no compute shaders and much lower limits, so a game that requires compute fails here there. To show a “WebGPU required” screen instead, set continue_without_requirements and check Graphics::unmet_requirements(), or ask with preferred_limits and check Graphics::supports_compute and ctx.gfx.device().limits() in Game::init.

Fields

adapter: String

The adapter’s name, as wgpu reports it.

backend: Backend

missing_limits: Vec<MissingLimit>

missing_features: Features

Trait Implementations

impl Clone for DeviceRequirementsError

fn clone(&self) -> DeviceRequirementsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceRequirementsError

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

Formats the value using the given formatter.

impl Eq for DeviceRequirementsError

impl Error for DeviceRequirementsError

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 DeviceRequirementsError

fn eq(&self, other: &DeviceRequirementsError) -> bool

Equality operator ==.

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

Inequality operator !=.
