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,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));

Variants

UnsignedInt(u64)

Represents positive fixint, uint 8, uint 16, uint 32 and uint 64

SignedInt(i64)

Represents negative fixint, int 8, int 16, int 32 and int 64

Float(f64)

Represents float 32 and float 64

Implementations

impl Number

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

If the Number is unsigned int, returns u64.

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

If the Number is signed int, returns i64.

pub fn as_float(&self) -> Option<f64>

If the Number is floating number, returns f64.

Trait Implementations

impl Clone for Number

fn clone(&self) -> Number

Returns a duplicate 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

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
