map_struct

A rust library to map raw data to a struct.

Usage

In Cargo.toml,

[dependencies]
map_struct = "0.1"

Implement unsafe Mappable trait to the struct to be mapped to a raw data:

#[repr(C)]
struct Hoge {
    a: u8,
    b: u8,
    c: u16,
}

unsafe impl Mappable for Hoge {}

Call mapped:

// mapped returns Option<(&Self, &[u8])>
Hoge::mapped(&[0x2, 0x3, 0x4, 0x5, 0x6])

mapped returns None if the argument length is not enough for the struct. It otherwise returns the tuple of the reference to the mapped struct and the rest of the data.
