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.

UnavailableGLState

The GLState object is unavailable.

That might occur if the current thread doesn’t support allocating a new graphics state. It might happen if you try to have more than one state on the same thread, for instance.

UnknownBlendingState(u8)

Corrupted blending state.

UnknownBlendingEquation(u32)

Corrupted blending equation.

UnknownBlendingSrcFactor(u32)

Corrupted blending source factor.

UnknownBlendingDstFactor(u32)

Corrupted blending destination factor.

UnknownDepthTestState(u8)

Corrupted depth test state.

UnknownStencilTestState(u8)

Corrupted stencil test state.

UnknownStencilTestComparison(i32)

Corrupted stencil test comparison.

UnknownStencilOp(i32)

Corrupted stencil op.

UnknownWriteState(u8)

Corrupted depth write state.

UnknownFaceCullingState(u8)

Corrupted face culling state.

UnknownFaceCullingOrder(u32)

Corrupted face culling order.

UnknownFaceCullingMode(u32)

Corrupted face culling mode.

UnknownVertexRestartState(u8)

Corrupted vertex restart state.

UnknownSRGBFramebufferState(u8)

Corrupted sRGB framebuffer state.

UnknownScissorState(u8)

Corrupted scissor state.

Trait Implementations

impl Debug for StateQueryError

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

Formats the value using the given formatter.

impl Display for StateQueryError

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

Formats the value using the given formatter.

impl Error for StateQueryError

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

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

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

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

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

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

impl From<StateQueryError> for GlutinError

fn from(e: StateQueryError) -> Self

Converts to this type from the input type.
