Enum SurfaceError 

#[non_exhaustive]
pub enum SurfaceError {
    #[non_exhaustive]
    ConfigureRetriesExhausted {
        last_error: String,
        unconfigured_for: Duration,
        attempts: u32,
    },
}

Why Gpu::try_acquire_frame could not produce frames any more.

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.

#[non_exhaustive]

ConfigureRetriesExhausted

The swap chain stayed unconfigured — every Surface::configure retry failing — for longer than crate::GpuConfig::surface_retry_budget. Returned again on every call until a configure succeeds (e.g. via Gpu::resize). The usual response is to exit with this error rather than keep a black window.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

last_error: String

wgpu’s text for the most recent failure.

unconfigured_for: Duration

From the first failure of the run to the most recent one.

attempts: u32

Consecutive failed configure attempts.

Trait Implementations

impl Clone for SurfaceError

fn clone(&self) -> Self

impl Eq for SurfaceError

impl Error for SurfaceError

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 SurfaceError

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

Equality operator ==.

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

Inequality operator !=.
