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.

Io(Error)

I/O Error

UnrecognizedToken(Option<(u64, usize)>, Option<SourceSpan>)

Lexer error

UnterminatedLiteral(Option<(u64, usize)>, Option<SourceSpan>)

Missing quote or double-quote or backtick

UnterminatedBracket(Option<(u64, usize)>, Option<SourceSpan>)

Missing ]

UnterminatedBlockComment(Option<(u64, usize)>, Option<SourceSpan>)

Missing */

BadVariableName(Option<(u64, usize)>, Option<SourceSpan>)

Invalid parameter name

BadNumber(Option<(u64, usize)>, Option<SourceSpan>, Option<usize>, String)

Invalid number format

ExpectedEqualsSign(Option<(u64, usize)>, Option<SourceSpan>)

Invalid or missing sign after !

MalformedBlobLiteral(Option<(u64, usize)>, Option<SourceSpan>)

BLOB literals are string literals containing hexadecimal data and preceded by a single “x” or “X” character.

MalformedHexInteger(Option<(u64, usize)>, Option<SourceSpan>, Option<usize>, Option<&'static str>)

Hexadecimal integer literals follow the C-language notation of “0x” or “0X” followed by hexadecimal digits.

ParserError(ParserError, Option<(u64, usize)>, Option<SourceSpan>)

Grammar error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Diagnostic for Error

fn help(&self) -> Option<Box<dyn Display + '_>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan> + '_>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn code<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn related<'a>( &'a self, ) -> Option<Box<dyn Iterator<Item = &'a dyn Diagnostic> + 'a>>

Additional related Diagnostics.

fn diagnostic_source(&self) -> Option<&dyn Diagnostic>

The cause of the error.

impl Display for Error

fn fmt(&self, f: &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.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ParserError> for Error

fn from(err: ParserError) -> Self

Converts to this type from the input type.

impl ScanError for Error

fn position(&mut self, line: u64, column: usize, offset: usize)

Update the position where the error occurs
