Information about the cause of an error.

Variants

EndOfFile

Whilst parsing as encountered an unexpected EOF.

InvalidProfile(String)

The shader specified an unsupported or invalid profile.

InvalidVersion(u64)

The shader requested an unsupported or invalid version.

InvalidToken(TokenValue, Vec<ExpectedToken>)

Whilst parsing an unexpected token was encountered.

A list of expected tokens is also returned.

NotImplemented(&'static str)

A specific feature is not yet implemented.

To help prioritize work please open an issue in the github issue tracker if none exist already or react to the already existing one.

UnknownVariable(String)

A reference to a variable that wasn’t declared was used.

UnknownType(String)

A reference to a type that wasn’t declared was used.

UnknownField(String)

A reference to a non existent member of a type was made.

UnknownLayoutQualifier(String)

An unknown layout qualifier was used.

If the qualifier does exist please open an issue in the github issue tracker if none exist already or react to the already existing one to help prioritize work.

UnsupportedMatrixTypeInStd140

Unsupported matrix of the form matCx2

Our IR expects matrices of the form matCx2 to have a stride of 8 however matrices in the std140 layout have a stride of at least 16

VariableAlreadyDeclared(String)

A variable with the same name already exists in the current scope.

SemanticError(Cow<'static, str>)

A semantic error was detected in the shader.

PreprocessorError(PreprocessorError)

An error was returned by the preprocessor.

InternalError(&'static str)

The parser entered an illegal state and exited

This obviously is a bug and as such should be reported in the github issue tracker

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Error for ErrorKind

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<ConstantEvaluatorError> for ErrorKind

fn from(err: ConstantEvaluatorError) -> Self

Converts to this type from the input type.
