Trait Packable

pub trait Packable:
    PartialEq

    + ToOwned<Owned: Debug + Clone + PartialEq>
    + PartialOrd {
    // Required methods
    fn width(item: &Self) -> usize;

Required Methods

fn width(item: &Self) -> usize

fn pack(item: &Self, out: &mut Vec<u8>)

fn unpack(buff: &[u8]) -> Result<(usize, Cow<'_, Self>), PackError>

Provided Methods

fn abs(_item: &Self) -> i64

fn agg(_item: &Self) -> Agg

fn maybe_agg(_item: &Option<Cow<'_, Self>>) -> Agg

fn validate(_val: Option<&Self>, _m: &ScanMeta) -> Result<(), PackError>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
