rend是一个库，它为Rust提供端序感知原语。

rend的实际应用

use rend::*;

let little_int = i32_le::from_native(0x12345678);
// Internal representation is little-endian
assert_eq!(
    [0x78, 0x56, 0x34, 0x12],
    unsafe { ::core::mem::transmute::<_, [u8; 4]>(little_int) }
);

// Can also be made with `.into()`
let little_int: i32_le = 0x12345678.into();
// Still formats correctly
assert_eq!("305419896", format!("{}", little_int));
assert_eq!("0x12345678", format!("0x{:x}", little_int));

let big_int = i32_be::from_native(0x12345678);
// Internal representation is big-endian
assert_eq!(
    [0x12, 0x34, 0x56, 0x78],
    unsafe { ::core::mem::transmute::<_, [u8; 4]>(big_int) }
);

// Can also be made with `.into()`
let big_int: i32_be = 0x12345678.into();
// Still formats correctly
assert_eq!("305419896", format!("{}", big_int));
assert_eq!("0x12345678", format!("0x{:x}", big_int));

lib.rs:

rend

rend是一个库，它为Rust提供跨平台的原语。

rend不提供跨平台的替代类型，例如内置跨平台的类型如bool和u8。它也不提供具有架构相关大小的类型的跨平台类型，如isize和usize。rend不支持自定义类型。

rend旨在用于构建可以在不同架构之间共享的可移植类型，特别是具有零拷贝反序列化的类型。

特性

• bytecheck：启用使用bytecheck验证类型的支持

示例

use rend::*;

let little_int = i32_le::from_native(0x12345678);
// Internal representation is little-endian
assert_eq!(
    [0x78, 0x56, 0x34, 0x12],
    unsafe { ::core::mem::transmute::<_, [u8; 4]>(little_int) }
);

// Can also be made with `.into()`
let little_int: i32_le = 0x12345678.into();
// Still formats correctly
assert_eq!("305419896", format!("{}", little_int));
assert_eq!("0x12345678", format!("0x{:x}", little_int));

let big_int = i32_be::from_native(0x12345678);
// Internal representation is big-endian
assert_eq!(
    [0x12, 0x34, 0x56, 0x78],
    unsafe { ::core::mem::transmute::<_, [u8; 4]>(big_int) }
);

// Can also be made with `.into()`
let big_int: i32_be = 0x12345678.into();
// Still formats correctly
assert_eq!("305419896", format!("{}", big_int));
assert_eq!("0x12345678", format!("0x{:x}", big_int));
