Enum OpenGLFilterError 

#[non_exhaustive]
pub enum OpenGLFilterError {
    InvalidOption(String),
    ContextCreation(String),
}

👎Deprecated since 0.11.0:

the OpenGL filter path is superseded by wgpu_filter (feature “wgpu”): it needs a display connection and converts colors on the CPU; see the module docs for migration

Errors from the OpenGLFrameFilter constructors (mirrors WgpuFilterError for the wgpu feature; converts into crate::error::Error::OpenGLFilter).

Runtime failures (shader compilation and linking, GL object creation, frame upload and readback) surface through the pipeline as FrameFilterError instead — this type covers what can go wrong before a frame flows.

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.

InvalidOption(String)

👎Deprecated since 0.11.0:

the OpenGL filter path is superseded by wgpu_filter (feature “wgpu”): it needs a display connection and converts colors on the CPU; see the module docs for migration

A constructor option is invalid: the fragment shader passed to new_simple is missing the in vec2 TexCoord; input that the default vertex shader feeds.

ContextCreation(String)

👎Deprecated since 0.11.0:

the OpenGL filter path is superseded by wgpu_filter (feature “wgpu”): it needs a display connection and converts colors on the CPU; see the module docs for migration

Surfman could not provide a GL device or context: no display connection, no usable adapter, or the requested GL version is unsupported.

Trait Implementations

impl Debug for OpenGLFilterError

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

Formats the value using the given formatter.

impl Display for OpenGLFilterError

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

Formats the value using the given formatter.

impl Error for OpenGLFilterError

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<OpenGLFilterError> for Error

Available on crate feature opengl only.

fn from(err: OpenGLFilterError) -> Self

Converts to this type from the input type.
