Enum WebGlProgramError 

pub enum WebGlProgramError {
    ShaderCompile(String),
    ProgramLink(String),
}

Errors that can occur while building a WebGL shader program.

Each variant carries the browser-provided info log so the caller can surface the exact GLSL diagnostic without losing fidelity.

Variants

ShaderCompile(String)

Vertex or fragment shader compilation failed.

Carries the shader info log returned by getShaderInfoLog.

ProgramLink(String)

Program linking failed (or createProgram returned None).

Carries the program info log returned by getProgramInfoLog.

Trait Implementations

impl Clone for WebGlProgramError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebGlProgramError

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

Formats the value using the given formatter.

impl Display for WebGlProgramError

Implements the formatted message for WebGlProgramError.

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

Formats the WebGlProgramError via the supplied formatter.

The browser’s own info log is appended verbatim, because a GLSL diagnostic is only actionable in the driver’s own wording.

Arguments

• &mut Formatter<'_> - The formatter receiving the formatted output.

Returns

• fmt::Result - Result of the formatting operation.

impl Error for WebGlProgramError

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.
