Struct SqlWriteProfiler 

pub struct SqlWriteProfiler { /* private fields */ }

A bounded, clone-shared observer for successful physical SQL write batches.

Installing this observer enables write-phase timing. A runtime without an observer does not read the clock or synchronize on the profiling path.

Implementations

impl SqlWriteProfiler

pub fn new(capacity: usize) -> Self

Creates an observer that retains at most capacity of the newest samples.

Panics

Panics when capacity is zero.

pub fn snapshot(&self) -> SqlWriteProfileSnapshot

pub fn drain(&self) -> SqlWriteProfileSnapshot

Returns and clears retained samples while preserving the cumulative dropped count.
