Enum Event 

pub enum Event {
    Started {
        oid: String,
        size: u64,
    },
    Progress {
        oid: String,
        bytes_done: u64,
    },
    Completed {
        oid: String,
    },
    Failed {
        oid: String,
        error: String,
    },
}

Per-object lifecycle events emitted by Transfer::download and Transfer::upload.

Sent on the optional tokio::sync::mpsc::UnboundedSender passed in by the caller. Order across objects is unspecified; events for a single object are ordered (Started → Progress* → Completed | Failed).

Failed carries a stringified error so the typed TransferError can still be moved into Report; events are for display, the report is authoritative.

Variants

Started

Transfer for oid is about to start.

size is the byte count the server reported (or the local size, for uploads).

Fields

oid: String

size: u64

Progress

bytes_done cumulative bytes have moved for this object so far.

May fire many times per object; consumers should treat values as monotonically non-decreasing.

Fields

oid: String

bytes_done: u64

Completed

Transfer succeeded.

For downloads, bytes are in the store and hash-verified; for uploads, the server’s verify callback (if any) has returned 2xx.

Fields

oid: String

Failed

Transfer failed after exhausting retries.

Fields

oid: String

error: String
