Implementations

impl LockStats

pub fn new() -> Self

Create new empty lock statistics.

pub fn avg_read_wait_ms(&self) -> f64

Calculate average read wait time in milliseconds.

pub fn avg_write_wait_ms(&self) -> f64

Calculate average write wait time in milliseconds.

pub fn read_contention_rate(&self) -> f64

Calculate read contention rate (0.0 to 1.0).

pub fn write_contention_rate(&self) -> f64

Calculate write contention rate (0.0 to 1.0).

pub fn commit_rate(&self) -> f64

Calculate transaction commit rate (0.0 to 1.0).
