Struct FrameHeader 

pub struct FrameHeader {
    pub flags: u8,
    pub algorithm: Algorithm,
    pub file_id: u32,
    pub chunk_index: u64,
    pub epoch: u32,

}

Fields

flags: u8

algorithm: Algorithm

file_id: u32

chunk_index: u64

epoch: u32

Bumped when a chunk is re-encoded, keeping (key, nonce) pairs unique.

raw_len: u32

Plaintext length before compression.

payload_len: u32

On-wire payload length, excluding the AEAD tag.
