Struct Estimate 

pub struct Estimate {
    pub id: String,
    pub config: String,
    pub cost: f64,
    pub occupancy: f64,
    pub waves: f64,
    pub smem_bytes: u64,
    pub kind: &'static str,
}

One candidate’s estimate. cost is a unitless relative score within a kernel’s space — smaller is predicted faster. It is NOT a time.

Fields

id: String

The candidate’s canonical config.v1 ID, matching verdicts.v1 and results.v1 for the same configuration.

config: String

Human-readable dimension assignments, e.g. block_x=128 tile=256.

cost: f64

Relative score, smaller predicted faster. Unitless, comparable only within one kernel’s space, and not a time — see docs/LIMITATIONS.md for the measured rank correlation.

occupancy: f64

Achieved occupancy in 0.0..=1.0: resident warps over the device maximum, capped at 1.

waves: f64

Grid blocks divided by the blocks resident across all SMs, floored at 1 — how many times the whole machine must be refilled.

smem_bytes: u64

Static shared memory this configuration requests, in bytes.

kind: &'static str

Always “estimated” (docs/LIMITATIONS.md); serialized so every surface carries it.

Trait Implementations

impl Clone for Estimate

fn clone(&self) -> Estimate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Estimate

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

Formats the value using the given formatter.

impl Serialize for Estimate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
