Enum ParseError

#[non_exhaustive]
pub enum ParseError {
    Empty,
    Syntax(usize, String),
    Overflow,
    TimeUnit(usize, String),
    NegativeExponentOverflow,
    PositiveExponentOverflow,
    NegativeNumber,
    InvalidInput(String),
}

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. TODO: Rename to positive overflow TODO: Add NegativeOverflow

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 Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParseError

fn deserialize<__D>( __deserializer: __D, ) -> Result<ParseError, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParseError

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

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<TryFromDurationError> for ParseError

fn from(error: TryFromDurationError) -> ParseError

Converts to this type from the input type.

impl Hash for ParseError

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl Serialize for ParseError

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ParseError

impl StructuralPartialEq for ParseError
