Rust library providing Zc for self-referential zero-copy structures.
Documentation hosted on docs.rs.

zc = "0.4"

Usage

use zc::Dependant;

#[derive(PartialEq, Debug, Dependant)]
pub struct StructWithBytes<'a>(&'a [u8]);

impl<'a> From<&'a [u8]> for StructWithBytes<'a> {
    fn from(bytes: &'a [u8]) -> Self {
        Self(&bytes[1..])
    }
}

fn main() {
    let owner = vec![1, 2, 3];
    let data = zc::from!(owner, StructWithBytes, [u8]);

    assert_eq!(
        data.get::<StructWithBytes>(),
        &StructWithBytes(&[2, 3])
    )
}
