Struct QueryProgress 

pub struct QueryProgress {
    pub percentage: f64,
    pub rows_processed: u64,
    pub total_rows_to_process: u64,
}

A thread-safe handle for interrupting or observing one running query. A snapshot of a running query’s progress.

Values mirror DuckDB’s duckdb_query_progress_type. percentage is -1.0 when DuckDB cannot estimate progress (e.g. progress reporting disabled, or no query running).

Fields

percentage: f64

Completion in 0.0..=100.0, or -1.0 when unknown.

rows_processed: u64

Rows processed so far.

total_rows_to_process: u64

Total rows the query expects to process.

Trait Implementations

impl Clone for QueryProgress

fn clone(&self) -> QueryProgress

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for QueryProgress

impl Debug for QueryProgress

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for QueryProgress

fn eq(&self, other: &QueryProgress) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
