Enum ParseError

pub enum ParseError {
    PositionMismatch,
    InvalidPosition(PositionError),
    Empty,
    IncontinuousRange,
    FailWildcard(ParseIntError),
    FailLiteral(ParseIntError),
    InvalidBoolean(String),
    FailRegex,
}

Errors from jlabel-question.

Variants

PositionMismatch

Some patterns are pointing at position different from which the first pattern is pointing at.

InvalidPosition(PositionError)

The pattern failed to parse.

Empty

The pattern or range is empty, so jlabel-question cannot parse it.

IncontinuousRange

The range is incontinuous or not arranged in ascending order.

FailWildcard(ParseIntError)

Failed to parse integer field in a pattern containing wildcard. This might result from incorrect number of wildcards.

FailLiteral(ParseIntError)

Failed to parse integer field in a pattern without wildcard. This might result from incorrect position of wildcard such as 1?2.

InvalidBoolean(String)

Failed to parse boolean field. Boolean fields must be either 0 or 1 (except for xx which means empty).

FailRegex

Available on crate feature regex only.

Failed to build regex parser from the pattern.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<PositionError> for ParseError

fn from(source: PositionError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> 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.
