Provides a macro to allows creation of a simple byte-array backed structs. Such struct has a predefined size and allocated on stack.
[dependencies]
byte-array-struct = "0.2"
``
// create struct named Address backed by [u8; 24]
// basically a shortcut topub struct Address([u8; 24]);`
bytearraystruct!(
pub struct Address(24);
);
impl Address { // any additional functionality for Address type }
// passed as a value on stack fn send(to: Address) { // ... }
fn main() { //accepts hex, which can also be prefixed with 0x let foo = Address::from_str("0123456789abcdef0123456789abcdef0123456789abcdef").unwrap();
send(foo); } ```
Macro provides implementation for following traits:
.deref().from_str(s), which accepts a hex string with the length of target array; may be optionally prefixed with 0x.to_string().from([u8; ...]) and .from(&[u8; ...]), where ... is the defined size.try_from(Vec<u8>) and .try_from(&[u8]).into(Vec<u8>) and .into([u8; ...]).serialize and .deserialize for Serde, with with-serde feature enabled (not enabled by default)with-serde to implement serialization/deserialization with Serde. Uses Hex encoded strings.
