Struct Progress 

#[non_exhaustive]
pub struct Progress {
    pub bytes_done: u64,
    pub bytes_total: Option<u64>,
    pub rate: f64,
    pub eta: Option<Duration>,
    pub elapsed: Duration,
}

Per-tick progress snapshot delivered to Reporter::report (FR-045).

#[non_exhaustive] allows additive fields in SemVer-minor releases per FR-056. Downstream code MUST NOT exhaustively match or construct via struct-literal syntax outside the defining crate.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

bytes_done: u64

Bytes transferred so far.

bytes_total: Option<u64>

Expected total bytes, if known.

rate: f64

Smoothed instantaneous rate in bytes/second (non-negative).

eta: Option<Duration>

Estimated time remaining (None when total is unknown OR rate is 0).

elapsed: Duration

Monotonic wall-clock time since the copy loop began.
