An individual error that occurred while parsing a filterset.

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

An invalid regex was encountered.

Fields

span: SourceSpan

The part of the input that failed.

message: String

A message indicating the failure.

InvalidGlob

An invalid glob pattern was encountered.

Fields

span: SourceSpan

The part of the input that failed.

error: GlobConstructError

The underlying error.

BannedPredicate

A banned predicate was encountered.

Fields

kind: FiltersetKind

The kind of expression.

span: SourceSpan

The span of the banned predicate.

reason: BannedPredicateReason

The reason why the predicate is banned.

InvalidRegexWithoutMessage(SourceSpan)

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

ExpectedCloseRegex(SourceSpan)

A regex string was not closed.

InvalidOrOperator(SourceSpan)

An unexpected OR operator was found.

InvalidAndOperator(SourceSpan)

An unexpected AND operator was found.

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.

InvalidEscapeCharacter(SourceSpan)

An invalid escape character was found.

ExpectedExpr(SourceSpan)

An expression was expected in this position but not found.

ExprFoundBinaryOp

A binary operator keyword or sigil was used in a position where an expression was expected.

Filterset binary operators are infix operators, not prefix ones. The suggest field is the canonical recognized form of the operator, used to nudge the user toward valid syntax in a single step: for AND it’s and, for && it’s &, and so on.

Fields

op: &'static str

The matched operator, exactly as it appeared in the input.

suggest: &'static str

The canonical recognized form to suggest in the help.

span: SourceSpan

The span of the operator.

ExprFoundUnaryOp

A unary-operator-shaped token was used in a syntax filtersets don’t recognize, e.g. uppercase NOT instead of not.

The suggest field is the canonical recognized form.

Fields

op: &'static str

The matched token, exactly as it appeared in the input.

suggest: &'static str

The canonical recognized form to suggest in the help.

span: SourceSpan

The span of the token.

ExpectedEndOfExpression(SourceSpan)

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

NoPackageMatch(SourceSpan)

This matcher didn’t match any packages.

NoGroupMatch(SourceSpan)

This matcher didn’t match any test groups.

NoBinaryIdMatch(SourceSpan)

This matcher didn’t match any binary IDs.

NoBinaryNameMatch(SourceSpan)

This matcher didn’t match any binary names.

InvalidPlatformArgument(SourceSpan)

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

UnsupportedExpression(SourceSpan)

Contained an unsupported expression.

Unknown

An unknown parsing error occurred.

Trait Implementations

impl Clone for ParseSingleError

fn clone(&self) -> ParseSingleError

Returns a duplicate 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 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 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)>

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 PartialEq for ParseSingleError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
