Enum Control 

pub enum Control {
    Manifest(Vec<FileEntry>),
    ResumeState(Vec<ResumeEntry>),
    LocalIndex(Vec<LocalFileIndex>),
    Start {
        streams: u32,
    },
    FileComplete {
        file_id: u32,
        hash: Option<[u8; 32]>,

}

Variants

Manifest(Vec<FileEntry>)

ResumeState(Vec<ResumeEntry>)

LocalIndex(Vec<LocalFileIndex>)

What the receiver already holds, chunk by chunk, for files that exist at the destination.

Sent by the receiver so the sender can recognise a chunk it is about to send as one the far side already has, and say so in 28 bytes instead. Hashing happens on the side that owns the old copy, and the sender compares against hashes it computes anyway for the integrity root — so neither end reads anything twice.

Start

Sender announces how many unidirectional data streams it will open, so the receiver accepts exactly that many and knows when to stop.

Fields

streams: u32

FileComplete

Every chunk of file_id has been handed to a data stream. hash is the Merkle root over the file’s chunk hashes, when verification is enabled.

Fields

file_id: u32

hash: Option<[u8; 32]>

AllComplete

Abort

Fields

reason: String
