Enum glium::ReadError

pub enum ReadError {
    OutputFormatNotSupported,
    AttachmentTypeNotSupported,
    ClampingNotSupported,
}

Error that can happen while reading.

Variants

OutputFormatNotSupported

The implementation doesn’t support converting to the requested output format.

OpenGL supports every possible format, but OpenGL ES only supports (u8, u8, u8, u8) and an implementation-defined format.

AttachmentTypeNotSupported

The implementation doesn’t support reading a depth, depth-stencil or stencil attachment.

OpenGL ES only supports reading from color buffers by default. There are extensions that allow reading other types of attachments.

ClampingNotSupported

Clamping the values is not supported by the implementation.

Trait Implementations

impl Debug for ReadError

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

Formats the value using the given formatter.

impl Display for ReadError

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

Formats the value using the given formatter.

impl Error for ReadError

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.
