Trait tor_cell::relaycell::RelayCellFields

pub trait RelayCellFields {
    const RECOGNIZED_RANGE: Range<usize>;
    const DIGEST_RANGE: Range<usize>;
    const EMPTY_DIGEST: &'static [u8];
}

Specifies field layout for a particular relay cell format.

Required Associated Constants

const RECOGNIZED_RANGE: Range<usize>

The range containing the recognized field, within a relay cell’s body.

const DIGEST_RANGE: Range<usize>

The range containing the digest field, within a relay cell’s body.

const EMPTY_DIGEST: &'static [u8]

A static array of zeroes of the same size as this format uses for the digest field. e.g. this enables updating a comparison-digest in one hash-update method call, instead of having to loop over DIGEST_RANGE.

Object Safety

This trait is not object safe.
