Enum NumberError

#[non_exhaustive]
pub enum NumberError {
    Empty,
    InvalidDigit,
    TooLarge,
    TooSmall,
    Zero,
}

An error that relates to parsing a number

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

The parsed string is empty

InvalidDigit

The parsed string contains a character that isn’t a digit

TooLarge

The number is too large to fit in the target integer type

TooSmall

The number is too small to fit in the target integer type

Zero

The number is zero, but the target number type can’t be zero

Trait Implementations

impl Clone for NumberError

fn clone(&self) -> NumberError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberError

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

Formats the value using the given formatter.

impl Display for NumberError

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

Formats the value using the given formatter.

impl Error for NumberError

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<NumberError> for ParseErrorKind

fn from(e: NumberError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for NumberError

fn from(e: ParseIntError) -> Self

Converts to this type from the input type.

impl PartialEq for NumberError

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