An individual error that occurred while parsing a filter expression.

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.

InvalidRegex

Fields

span: SourceSpan

The part of the input that failed.

message: String

A message indicating the failure.

An invalid regex was encountered.

InvalidRegexWithoutMessage(SourceSpan)

An invalid regex was encountered but we couldn’t determine a better error message.

ExpectedCloseRegex(SourceSpan)

A regex string was not closed.

UnexpectedArgument(SourceSpan)

An unexpected argument was found.

UnexpectedComma(SourceSpan)

An unexpected comma was found.

InvalidString(SourceSpan)

An invalid string was found.

ExpectedOpenParenthesis(SourceSpan)

An open parenthesis ( was expected but not found.

ExpectedCloseParenthesis(SourceSpan)

A close parenthesis ) was expected but not found.

ExpectedExpr(SourceSpan)

An expression was expected in this position but not found.

ExpectedEndOfExpression(SourceSpan)

The expression was expected to end here but some extra text was found.

NoPackageMatch(SourceSpan)

This matcher didn’t match any packages.

InvalidPlatformArgument(SourceSpan)

Expected “host” or “target” for a platform() predicate.

Unknown

An unknown parsing error occurred.

Trait Implementations

impl Clone for ParseSingleError

fn clone(&self) -> ParseSingleError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseSingleError

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

Formats the value using the given formatter.

impl Diagnostic for ParseSingleError

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

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

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

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 help(&'a self) -> Option<Box<dyn Display + 'a, Global>>

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

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

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

Additional related Diagnostics.

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

The cause of the error.

impl Display for ParseSingleError

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

Formats the value using the given formatter.

impl Error for ParseSingleError

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

impl PartialEq<ParseSingleError> for ParseSingleError

fn eq(&self, other: &ParseSingleError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ParseSingleError) -> bool

This method tests for !=.
