Trait Packable

pub trait Packable: Sized {
    // Required methods
    fn len() -> usize;
    fn pack(self, buffer: &mut [u8]) -> Result<(), PackingError>;
    fn unpack(data: &[u8]) -> Result<Self, PackingError>;
}

Trait implemented by data to be sent over network boundaries.

Required Methods

fn len() -> usize

Get the minimum necessary length of a buffer to pack this data into.

fn pack(self, buffer: &mut [u8]) -> Result<(), PackingError>

Pack a given piece of data into a given buffer.

Note: this format of pack was utilized to make this trait compatible with both std and no_std targets (specifically for no_std targets without alloc)

fn unpack(data: &[u8]) -> Result<Self, PackingError>

Unpack a given piece of data from an array of bytes

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.
