EGL errors.

Variants

NotInitialized

EGL is not initialized, or could not be initialized, for the specified EGL display connection.

BadAccess

EGL cannot access a requested resource (for example a context is bound in another thread).

BadAlloc

EGL failed to allocate resources for the requested operation.

BadAttribute

An unrecognized attribute or attribute value was passed in the attribute list.

BadContext

An Context argument does not name a valid EGL rendering context.

BadConfig

An Config argument does not name a valid EGL frame buffer configuration.

BadCurrentSurface

The current surface of the calling thread is a window, pixel buffer or pixmap that is no longer valid.

BadDisplay

An Display argument does not name a valid EGL display connection.

BadSurface

An Surface argument does not name a valid surface (window, pixel buffer or pixmap) configured for GL rendering.

BadMatch

Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface).

BadParameter

One or more argument values are invalid.

BadNativePixmap

A NativePixmapType argument does not refer to a valid native pixmap.

BadNativeWindow

A NativeWindowType argument does not refer to a valid native window.

ContextLost

A power management event has occurred. The application must destroy all contexts and reinitialise OpenGL ES state and objects to continue rendering.

Implementations

impl Error

pub fn native(&self) -> Int

Trait Implementations

impl Clone for Error

pub fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Int

pub fn from(e: Error) -> Int

Performs the conversion.

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl StructuralEq for Error

impl StructuralPartialEq for Error

impl TryFrom<i32> for Error

type Error = Int

The type returned in the event of a conversion error.

pub fn try_from(e: Int) -> Result<Error, Int>

Performs the conversion.
