Error type emitted during the parsing

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.

Empty

Returned, if the input was empty.

Syntax(usize, String)

A syntax error. Syntax errors report the position (column) where it was encountered and a reason.

Overflow

Currently only used internally for overflows of the maximum Duration.

TimeUnit(usize, String)

An error concerning time units. Like ParseError::Syntax the position where the error occurred is included.

NegativeExponentOverflow

The exponent exceeded the minimum negative exponent (-32768)

PositiveExponentOverflow

The exponent exceeded the maximum positive exponent (+32767)

NegativeNumber

The input number was negative. Note that numbers close to 0 (< 1e-18) are not negative but resolve to 0`

InvalidInput(String)

A generic error if no other error type fits

Trait Implementations

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl PartialEq<ParseError> for ParseError

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

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

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

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