Struct TransferProgress 

struct TransferProgress {
    resumed_from: HashMap<String, u64>,
    in_flight: HashMap<String, (u64, u64)>,
    cancelling: Option<String>,
}

Per-file transfer bookkeeping, kept across the progress events of one prepare call.

Keyed by file throughout because the models are prepared concurrently and their events interleave: a single slot lets one model’s Verifying clear the other’s resume marker mid-transfer, and lets a model that already finished be named as the one a cancellation stopped.

Fields

resumed_from: HashMap<String, u64>

What a .part held when its transfer opened. A bar that starts at 38% with nothing said about it reads as a bug.

in_flight: HashMap<String, (u64, u64)>

Bytes seen so far per file still transferring.

cancelling: Option<String>

Which transfer a cancellation is reported against. With one model in flight this names the same file the old single slot did.

Implementations

impl TransferProgress

fn apply(&mut self, progress: Progress) -> (String, DictateModelState)

Fold one event in and return the row state it implies.

fn cancellation(&self) -> (String, u64, u64)

The file a cancellation is about and how far it got. An empty name when nothing was transferring, which names no row and shows no bytes rather than blaming a model that finished.

Trait Implementations

impl Default for TransferProgress

fn default() -> Self

Returns the “default value” for a type.
