Enum Error

pub enum Error {
    InvalidEnum,
    InvalidValue,
    InvalidOperation,
    Unavailable,
    StackOverflow,
    StackUnderflow,
    OutOfMemory,
    InvalidFramebufferOperation,
    ShaderError(String),
}

An error that may be returned from an OpenGL operation.

This is normally retrieved by calling glGetError, which is mapped to Error::last_error.

Variants

InvalidEnum

InvalidValue

InvalidOperation

Unavailable

StackOverflow

StackUnderflow

OutOfMemory

InvalidFramebufferOperation

ShaderError(String)

Implementations

impl Error

pub fn last_error() -> Option<Self>

Returns the last error that occurred by calling glGetError.

pub fn from_gl_status(code: GLuint) -> Option<Self>

Creates a new error from a GLEW error code.

Parameters

• code - The error code to create the error from

pub unsafe fn from_gl_status_unchecked(code: GLuint) -> Self

Creates a new error from a GLEW error code without checking

Parameters

• code - The error code to create the error from

Safety

The error code must be one of the valid error codes.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
