Error type for source preprocessing.

Variants

MissingVersionHeader

The version header was not found in the source file.

IOError(PathBuf, Error)

An IO error occurred when reading the source file.

EncodingError(PathBuf)

A known encoding was not found for the file.

UnexpectedEof

Unexpected EOF when reading the source file.

UnexpectedEol(usize)

Unexpected end of line when reading the source file.

PragmaParseError(String)

An error occurred when parsing a pragma statement.

DuplicatePragmaError(String)

The given pragma was declared multiple times with differing values.

UnknownImageFormat

The image format requested by the shader was unknown or not supported.

InvalidStage

The stage declared by the shader source was not vertex or fragment.

Trait Implementations

impl Debug for PreprocessError

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

Formats the value using the given formatter.

impl Display for PreprocessError

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

Formats the value using the given formatter.

impl Error for PreprocessError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Infallible> for PreprocessError

fn from(_: Infallible) -> Self

Converts to this type from the input type.
