Enum Error 

pub enum Error {
    VersionNotSupported,
    NoAvailablePixelFormat,
    GraphicsAdapterNotFound {
        backend: &'static str,
        reason: Reason,
    },
    BackendError(String),
    List(Vec<Self>),
}

An error that occurred while creating an application’s graphical context.

Variants

VersionNotSupported

The requested backend version is not supported.

NoAvailablePixelFormat

Failed to find any pixel format that matches the criteria.

GraphicsAdapterNotFound

A suitable graphics adapter or device could not be found.

Fields

backend: &'static str

The name of the backend where the error happened

reason: Reason

The reason why this backend could not be used

BackendError(String)

An error occurred in the context’s internal backend

List(Vec<Self>)

Multiple errors occurred

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

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