Enum LayoutError

#[non_exhaustive]
pub enum LayoutError {
    TooManyMipMaps(u32),
    MissingDepth,
    ZeroDimension,
    ArraySizeTooBig(u32),
    DataLayoutTooBig,
    InvalidCubeMapFaces,
}

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.

TooManyMipMaps(u32)

The decoder only supports up to 255 mipmaps.

In practice, texture will have at most 32 mipmaps, so this limitation should only affect invalid/malicious files.

MissingDepth

A volume/texture 3D without a depth.

ZeroDimension

The width, height, or depth of the texture is zero.

ArraySizeTooBig(u32)

The array_size field is too large.

It either exceeds a user-defined limit or causes an overflow for cube map faces.

DataLayoutTooBig

The header of the DDS file describes a data section that is too large.

I.e. it is possible for the header to describe a texture that requires >2^64 bytes of memory.

InvalidCubeMapFaces

The faces of a cube map must always be 2D textures.

Trait Implementations

impl Debug for LayoutError

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

Formats the value using the given formatter.

impl Display for LayoutError

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

Formats the value using the given formatter.

impl Error for LayoutError

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<LayoutError> for DecodingError

fn from(error: LayoutError) -> Self

Converts to this type from the input type.

impl From<LayoutError> for EncodingError

fn from(err: LayoutError) -> Self

Converts to this type from the input type.
