Enum GenericSurfaceError 

#[non_exhaustive]
pub enum GenericSurfaceError {
    Init(String),
    Present(String),
}

A ready-made, string-backed SurfaceError for presenters whose underlying surface library reports failures as opaque strings rather than a structured error enum.

Several presenter backends (e.g. retroglyph-gl’s native/wasm split, or a future softbuffer backend) need only two buckets (“surface/context creation failed” (fatal) and “presenting a frame failed” (potentially recoverable)) and would otherwise each hand-roll the same enum { Init(String), Present(String) } plus RecoverableError impl. This type is that common shape, provided once here so backends can reuse it directly instead of duplicating it.

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.

Init(String)

Creating the surface or its underlying context failed. Treated as fatal (not recoverable): a presenter cannot proceed without a surface, and retrying the same creation path is very unlikely to succeed.

Present(String)

Presenting a frame failed. Treated as potentially recoverable so the event loop’s consecutive-failure heuristic can retry before giving up.

Trait Implementations

impl Debug for GenericSurfaceError

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

Formats the value using the given formatter.

impl Display for GenericSurfaceError

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

Formats the value using the given formatter.

impl Error for GenericSurfaceError

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 RecoverableError for GenericSurfaceError

fn is_recoverable(&self) -> bool

Whether this error represents a transient failure worth retrying, as opposed to a fatal one.
