Enum Number

pub enum Number {
    UnsignedInt(u64),
    SignedInt(i64),
    Float(f64),
}

Represents any number, it could be int or float.

Example

use serde::{Deserialize, Serialize};
use messagepack_serde::{from_slice,value::Number};
#[derive(Debug, Serialize, Deserialize, PartialEq)]
struct Data{
    num: Number
}
let buf:&[u8] = &[0x81,0xa3,0x6e,0x75,0x6d,0x01]; // {"num":1}
let data = from_slice::<Data>(buf).unwrap();
assert_eq!(data.num,Number::UnsignedInt(1));

let buf:&[u8] = &[0x81,0xa3,0x6e,0x75,0x6d,0xd0,0x85]; // {"num":-123}
let data = from_slice::<Data>(buf).unwrap();
assert_eq!(data.num,Number::SignedInt(-123));

let buf:&[u8] = &[0x81,0xa3,0x6e,0x75,0x6d,0xcb,0x3f,0xf8,0x00,0x00,0x00,0x00,0x00,0x00]; // {"num":1.5}
let data = from_slice::<Data>(buf).unwrap();
assert_eq!(data.num,Number::Float(1.5));

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: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<f32> for Number

fn from(value: f32) -> 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<i16> for Number

fn from(value: i16) -> Self

Converts to this type from the input type.

impl From<i32> for Number

fn from(value: i32) -> 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<i8> for Number

fn from(value: i8) -> Self

Converts to this type from the input type.

impl From<u16> for Number

fn from(value: u16) -> Self

Converts to this type from the input type.

impl From<u32> for Number

fn from(value: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Number

fn from(value: u64) -> Self

Converts to this type from the input type.

impl From<u8> for Number

fn from(value: u8) -> Self

Converts to this type from the input type.

impl PartialEq for Number

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

fn partial_cmp(&self, other: &Number) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Number

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Number

impl StructuralPartialEq for Number
