Trait engine_traits::perf_context::PerfContextExt[−][src]

pub trait PerfContextExt {
    type PerfContext: PerfContext;
    fn get_perf_context(
        &self, 
        level: PerfLevel, 
        kind: PerfContextKind
    ) -> Self::PerfContext;
}

Extensions for measuring engine performance.

A PerfContext is created with a specific measurement level, and a ‘kind’ which represents wich tikv subsystem measurements are being collected for.

In rocks, PerfContext uses global state, and does not require access through an engine. Thus perf data is not per-engine. This doesn’t seem like a reasonable assumption for engines generally, so this abstraction follows the existing pattern in this crate and requires PerfContext to be accessed through the engine.
