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The current surface of the calling thread is a window, pixel buffer or pixmap that is no longer valid.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

fn from(e: Error) -> Int

Converts to this type from the input type.
source§

impl PartialEq for Error

source§

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