Enum GlInitError 

#[non_exhaustive]
pub enum GlInitError {
    DisplayBuild(String),
    NoWindow,
    WindowHandle(String),
    ContextCreation(Error),
    SurfaceAttributes(String),
    SurfaceCreation(Error),
    MakeCurrent(Error),
}

Errors that can occur during OpenGL / window initialization.

Each variant represents a distinct step in the initialization pipeline.

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.

DisplayBuild(String)

The windowing / display builder failed to initialize.

NoWindow

The display builder succeeded but did not produce a window.

WindowHandle(String)

Failed to obtain the native window handle.

ContextCreation(Error)

OpenGL context creation failed. Wraps glutin::error::Error.

SurfaceAttributes(String)

Window surface attributes could not be constructed.

SurfaceCreation(Error)

Rendering surface creation failed. Wraps glutin::error::Error.

MakeCurrent(Error)

Making the GL context current on the surface failed. Wraps glutin::error::Error.

Trait Implementations

impl Clone for GlInitError

fn clone(&self) -> GlInitError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlInitError

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

Formats the value using the given formatter.

impl Display for GlInitError

Available on crate features viewer or renderer-winit-fallback only.

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

Formats the value using the given formatter.

impl Error for GlInitError

Available on crate features viewer or renderer-winit-fallback only.

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 From<GlInitError> for MjViewerError

Converts a GlInitError into MjViewerError::GlInitFailed.

fn from(e: GlInitError) -> Self

Converts to this type from the input type.

impl From<GlInitError> for RendererError

Available on crate feature renderer-winit-fallback only.

Converts a GlInitError into RendererError::GlInitFailed.

fn from(e: GlInitError) -> Self

Converts to this type from the input type.
