Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Number

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Number

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Number

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

Formats the value using the given formatter.

impl From<Number> for StringOrNumber

fn from(value: Number) -> Self

Converts to this type from the input type.

impl From<Number> for Value

fn from(value: Number) -> Self

Converts to this type from the input type.

impl From<f64> for Number

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i64> for Number

fn from(value: i64) -> Self

Converts to this type from the input type.

impl From<u64> for Number

impl FromStr for Number

type Err = ParseNumberError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl LowerExp for Number

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

impl PartialEq for Number

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

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