Errors that BLP parser can produce

Variants

WrongMagic(String)

Invalid magic bytes in BLP header

ExternalMipmap(usize, Box<dyn Error>)

Failed to load external mipmap file

MissingImage(usize)

Missing image data for the specified mipmap level

OutOfBounds

Image data extends beyond file boundaries

Fields

offset: usize

Offset where the out of bounds access occurred

size: usize

Size of data that was attempted to be read

Blp2NoExternalMips

BLP2 format does not support external mipmap files

Blp2UnknownCompression(u8)

Unsupported compression type in BLP2 header

Blp2UnknownAlphaType(u8)

Unsupported alpha channel type in BLP2 header

UnknownAlphaType(u8)

Unknown alpha type value during parsing

Blp2UnexpectedJpegCompression

Invalid combination of JPEG compression with direct content

UnexpectedEof

Unexpected end of file while parsing

Context(String, Box<Self>)

Parser error with context information

Implementations

impl Error

pub fn with_context(self, context: &str) -> Self

Add context information to an error

Trait Implementations

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, __formatter: &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.
