Enum JsonNumberTokenError 

#[non_exhaustive]
pub enum JsonNumberTokenError {
    Fractional,
    OutOfSafeIntegerRange,
}

Explains why a validated JSON number cannot be represented as a safe integer.

JsonNumberToken::exact_safe_integer returns this error when the exact decimal value is fractional or outside the IEEE-754 safe-integer range.

Examples

use qubit_json::decode::JsonNumberTokenError;

let error = JsonNumberTokenError::Fractional;
assert_eq!(error.to_string(), "number is fractional");

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.

Fractional

The token has a non-integral mathematical value.

OutOfSafeIntegerRange

The integer is outside the inclusive safe-integer range.

Trait Implementations

impl Clone for JsonNumberTokenError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for JsonNumberTokenError

impl Debug for JsonNumberTokenError

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

Formats the value using the given formatter.

impl Display for JsonNumberTokenError

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

Formats the error as a concise description of the failed conversion.

Fractional values and integers outside the safe range have distinct messages so callers can preserve the failure category in diagnostics.

Parameters

• formatter: Receives the formatted error text.

Returns

Returns Ok(()) when the message is written.

Errors

Returns the formatter’s error if writing the message fails.

impl Eq for JsonNumberTokenError

impl Error for JsonNumberTokenError

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 Hash for JsonNumberTokenError

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

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 JsonNumberTokenError

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

Equality operator ==.

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

Inequality operator !=.
