Trait AFastSerialize 

pub trait AFastSerialize {
    // Required method
    fn to_bytes(&self) -> Vec<u8> ;
}

序列化 trait，为类型提供转换为字节数组的能力。

Serialization trait that provides the ability to convert a type into a byte array.

编码规则 / Encoding Rules

实现者应确保 to_bytes() 输出的字节流能够被对应的 AFastDeserialize::from_bytes 完整还原。字节序统一使用 小端序 (little-endian)。

Implementors must ensure that the byte output of to_bytes() can be fully restored by the corresponding AFastDeserialize::from_bytes. All multi-byte values use little-endian byte order.

示例 / Example

use afastdata::AFastSerialize;

let value: i32 = 42;
let bytes = value.to_bytes();
assert_eq!(bytes, vec![42, 0, 0, 0]);

Required Methods

fn to_bytes(&self) -> Vec<u8>

将值序列化为字节数组。

Serialize the value into a byte array.

返回值 / Returns

返回一个 Vec<u8>，包含该值的完整二进制表示。

Returns a Vec<u8> containing the complete binary representation of the value.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl AFastSerialize for &str

fn to_bytes(&self) -> Vec<u8>

将字符串切片序列化为：LenInt 长度前缀 + UTF-8 字节。

Serializes the string slice as: LenInt length prefix + UTF-8 bytes.

与 String 的序列化格式完全一致，方便在不拥有所有权的情况下进行序列化。

Identical to String serialization format, allowing serialization without taking ownership.

impl AFastSerialize for String

fn to_bytes(&self) -> Vec<u8>

将字符串序列化为：LenInt 长度前缀 + UTF-8 字节。

Serializes the string as: LenInt length prefix + UTF-8 bytes.

长度前缀表示 UTF-8 字节的长度（不是字符数）。

The length prefix represents the number of UTF-8 bytes (not the character count).

impl AFastSerialize for bool

fn to_bytes(&self) -> Vec<u8>

将布尔值序列化为 1 个字节：true 为 0x01，false 为 0x00。

Serializes the boolean to 1 byte: true as 0x01, false as 0x00.

impl AFastSerialize for f32

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for f64

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for i8

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for i16

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for i32

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for i64

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for i128

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for u8

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for u16

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for u32

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for u64

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl AFastSerialize for u128

fn to_bytes(&self) -> Vec<u8>

将数值转为 $size 字节的 little-endian 字节数组。

Converts the value to a $size-byte little-endian byte array.

impl<T: AFastSerialize, const N: usize> AFastSerialize for [T; N]

fn to_bytes(&self) -> Vec<u8>

将固定大小数组序列化为：逐个元素的序列化数据，无长度前缀。

Serializes a fixed-size array as: element-wise serialized data with no length prefix.

因为数组大小在编译时已知，所以不需要长度前缀。

Since the array size is known at compile time, no length prefix is needed.

impl<T: AFastSerialize> AFastSerialize for Option<T>

fn to_bytes(&self) -> Vec<u8>

将 Option<T> 序列化。

Serializes an Option<T>.

• None：写入 0x00（1 字节）

• Some(value)：写入 0x01（1 字节标记）+ 值的序列化数据

• None: Writes 0x00 (1 byte)

• Some(value): Writes 0x01 (1 byte tag) + the serialized value data

impl<T: AFastSerialize> AFastSerialize for Vec<T>

fn to_bytes(&self) -> Vec<u8>

将向量序列化为：LenInt 元素个数前缀 + 逐个元素的序列化数据。

Serializes the vector as: LenInt element count prefix + serialized data for each element.

每个元素调用其自身的 to_bytes() 方法，所有元素的序列化结果依次拼接。

Each element’s to_bytes() method is called, and all serialized results are concatenated sequentially.
