Struct SlotStats 

pub struct SlotStats {
    pub plans: u64,
    pub warm_plans: u64,
    pub host_rows: u64,
    pub host_bytes: u64,
    pub device_rows: u64,
    pub device_bytes: u64,
}

Running totals for /metrics and for the A/B that says whether residency is paying for itself.

Fields

plans: u64

Plans applied, warm ones included.

warm_plans: u64

Plans that copied nothing at all.

host_rows: u64

Rows and bytes that crossed the link from host memory.

host_bytes: u64

device_rows: u64

Rows and bytes moved slot-to-slot without touching the host.

device_bytes: u64

Implementations

impl SlotStats

pub fn warm_plan_rate(&self) -> f64

Fraction of plans that moved nothing. The headline number for expert residency: at 1.0 the pool holds the whole working set and decode issues no weight traffic at all.

pub fn host_bytes_per_plan(&self) -> f64

Bytes that crossed the link per plan. What a link budget is spent against, and the figure a q* split is supposed to move.
