Trait Tag

pub(crate) trait Tag {
    type Buf: AsRef<[u8]> + AsMut<[u8]> + Debug + Unpin;

    const PATTERN: &'static [u8];

    // Required method
    fn make_buf() -> Self::Buf;
}

Tag defines a “trailer tag”: specific, fixed bytes that must follow wire data.

Required Associated Constants

const PATTERN: &'static [u8]

The expected suffix

The first 8 bytes may be ignored, and it must be an 8-byte aligned size.

Required Associated Types

type Buf: AsRef<[u8]> + AsMut<[u8]> + Debug + Unpin

Suitably sized buffer for reading Self::PATTERN

HACK: This is a workaround for const generics limitations.

Required Methods

fn make_buf() -> Self::Buf

Make an instance of Self::Buf

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.

Implementors
