Expand description

Progress snapshot for a write operation.

Implementations§

Source§

impl WriteProgress

Source

pub fn elapsed(&self) -> Duration

Wall-clock time since monitoring started.

Source

pub fn output_rows(&self) -> usize

Number of rows written so far.

Source

pub fn output_bytes(&self) -> usize

Number of bytes written so far.

Source

pub fn total_rows(&self) -> Option<usize>

Total rows expected.

Populated when the input source reports a row count (e.g. a arrow_array::RecordBatch). Always Some when WriteProgress::done is true — falling back to the actual number of rows written.

Source

pub fn active_tasks(&self) -> usize

Number of parallel write tasks currently in flight.

Source

pub fn total_tasks(&self) -> usize

Total number of parallel write tasks (i.e. the write parallelism).

Source

pub fn done(&self) -> bool

Whether the write operation has completed.

The final callback always has done = true. Callers can use this to finalize progress bars or perform cleanup.
