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.

Tuple Fields of InvalidProfile

0: String

InvalidVersion(u64)

The shader requested an unsupported or invalid version.

Tuple Fields of InvalidVersion

0: u64

InvalidToken(TokenValue, Vec<ExpectedToken>)

Whilst parsing an unexpected token was encountered.

A list of expected tokens is also returned.

Tuple Fields of InvalidToken

0: TokenValue1: Vec<ExpectedToken>

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.

Tuple Fields of NotImplemented

0: &'static str

UnknownVariable(String)

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

Tuple Fields of UnknownVariable

0: String

UnknownType(String)

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

Tuple Fields of UnknownType

0: String

UnknownField(String)

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

Tuple Fields of UnknownField

0: String

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.

0: String

VariableAlreadyDeclared(String)

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

Tuple Fields of VariableAlreadyDeclared

Tuple Fields of PreprocessorError

0: PreprocessorError

Trait Implementations

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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
