Struct OpStats 

pub struct OpStats {
    pub op_name: String,
    pub input_rows: u64,
    pub output_rows: u64,
    pub duration_us: u64,
    pub memory_bytes: u64,
}

Statistics for a single operation

Tracks the name, row counts, duration, and memory usage for an operation.

Fields

op_name: String

Name of the operation (e.g., “hash_join”, “filter”, “scan”)

input_rows: u64

Number of input rows processed

output_rows: u64

Number of output rows produced

duration_us: u64

Duration in microseconds

memory_bytes: u64

Memory used in bytes

Implementations

impl OpStats

pub fn new( op_name: impl Into<String>, input_rows: u64, output_rows: u64, duration_us: u64, memory_bytes: u64, ) -> Self

Create a new OpStats with all fields

pub fn timed( op_name: impl Into<String>, input_rows: u64, output_rows: u64, duration_us: u64, ) -> Self

Create OpStats for an operation with no memory tracking

Trait Implementations

impl Clone for OpStats

fn clone(&self) -> OpStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpStats

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

Formats the value using the given formatter.

impl Default for OpStats

fn default() -> OpStats

Returns the “default value” for a type.

impl PartialEq for OpStats

fn eq(&self, other: &OpStats) -> 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.
