The aim of this crate is to improve user experience when working with static bytes.
Look at this pseudo code example to understand problem with
&mut [u8] and
let mut fixed_storage = [u8; 16]; let mut slice = fixed_storage[..]; let len_before = slice.len(); // declaration fn encode(&self, buf: &mut dyn BufMut); frame.encode(&mut slice); let len = len_before - slice.len(); let filled_bytes = fixed_storage[..len];
There are two problems with code above:
- it will panic if encode want to use more than 16 bytes!
- it is boilerplate
You can resolve both with
SafeBytesSlice. For example usage see
- v0.1.x is compatible with bytes >=0.5.0, <0.6.0
- v0.2.x is compatible with bytes >=0.6.0, <0.7.0
- v0.3.x is compatible with bytes >=0.1.0, <2.0.0
