Enum OffscreenError 

pub enum OffscreenError {
    NoAdapter,
    Renderer(Error),
    ContextPoisoned,
}

Why an OffscreenRenderer could not be built.

Every variant is an environment failure. Bad arguments (a zero width or height) stay an assert! in the constructors — that’s a caller bug.

Variants

NoAdapter

On a headless machine this usually means no software rasteriser is installed (llvmpipe / lavapipe).

Renderer(Error)

ContextPoisoned

Only reachable under panic = "unwind"; the shipping release profile aborts instead of poisoning.

Trait Implementations

impl Debug for OffscreenError

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

Formats the value using the given formatter.

impl Display for OffscreenError

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

Formats the value using the given formatter.

impl Error for OffscreenError

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.
