Expand description

A single block transfer between the local node and a remote peer.

Fields§

§transfer_id: u64

Unique identifier for this transfer.

§cid: String

Content identifier of the block being transferred.

§peer_id: String

Identifier of the remote peer.

§direction: TransferDirection

Whether this node is uploading or downloading.

§total_bytes: u64

Total size of the block in bytes.

§chunk_size: u64

Maximum bytes per chunk (default 65536).

§state: TransferState

Current lifecycle state of the transfer.

§received_chunks: Vec<u32>

Indices of chunks that have been received or sent.

§started_at_tick: u64

Tick at which the transfer was started.

Implementations§

Source §

impl BlockTransfer

Source

pub fn total_chunks(&self) -> u32

Return the total number of chunks required for this transfer.

Uses ceiling division so that a partial last chunk is counted.

Source

pub fn progress(&self) -> f64

Return transfer progress as a fraction in [0.0, 1.0].

Returns 0.0 when the transfer is TransferState::Pending.

Source

pub fn is_complete(&self) -> bool

Return true if the transfer has reached TransferState::Completed.
