This crate provides macros to generate bitfield-like struct.
This a complete rewrite of the bitfield crate.
You can find the previous version in the rust-bitfield-legacy repository. This version works on the stable version of rustc and use a different syntax with different possibility.
An IPv4 header could be described like that:
rust
bitfield!{
struct IpV4Header(MSB0 [u8]);
u32;
get_version, _: 3, 0;
get_ihl, _: 7, 4;
get_dscp, _: 13, 8;
get_ecn, _: 15, 14;
get_total_length, _: 31, 16;
get_identification, _: 47, 31;
get_df, _: 49;
get_mf, _: 50;
get_fragment_offset, _: 63, 51;
get_time_to_live, _: 71, 64;
get_protocol, _: 79, 72;
get_header_checksum, _: 95, 79;
get_source_address, _: 127, 96;
get_destination_address, _: 159, 128;
}
In this exeample, all the field are read-only.
