Numeric(Numeric)

A numeric value.

Implementations

impl Value

pub fn deserialize<V: for<'de> Deserialize<'de>>(&self) -> Result<V, Error>

Deserializes the bytes contained inside of this value. Returns an error if this value doesn’t contain bytes.

pub fn as_i64_lossy(&self, saturating: bool) -> Option<i64>

Returns this value as an i64, allowing for precision to be lost if the type was not an i64 originally. If saturating is true, the conversion will not allow overflows. Returns None if the value is bytes.

pub fn as_u64_lossy(&self, saturating: bool) -> Option<u64>

Returns this value as an u64, allowing for precision to be lost if the type was not an u64 originally. If saturating is true, the conversion will not allow overflows. Returns None if the value is bytes.

pub const fn as_f64_lossy(&self) -> Option<f64>

Returns this value as an f64, allowing for precision to be lost if the type was not an f64 originally. Returns None if the value is bytes.

pub fn as_i64(&self) -> Option<i64>

Returns this numeric as an i64, allowing for precision to be lost if the type was not an i64 originally. Returns None if the value is bytes.

pub fn as_u64(&self) -> Option<u64>

Returns this numeric as an u64, allowing for precision to be lost if the type was not an u64 originally. Returns None if the value is bytes.

pub const fn as_f64(&self) -> Option<f64>

Returns this numeric as an f64, allowing for precision to be lost if the type was not an f64 originally. Returns None if the value is bytes.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<Value> for Value

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

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

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

This method tests for !=.

impl Serialize for Value

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

Serialize this value into the given Serde serializer.
