Struct TuneGroup 

pub struct TuneGroup<K> { /* private fields */ }

A priority bucket for tunables, computed from the autotune key.

Higher-priority groups are autotuned first; once any tunable in a group returns a valid result, no later groups are tried.

Implementations

impl<K> TuneGroup<K>

pub fn new(name: &str, f: impl Fn(&K) -> i8 + Send + Sync + 'static) -> Self

Create a new group based on a priority function.

A member’s own priority (Tunable::group) is a cutoff: the highest level is the round, and the levels under it are fallbacks reached as each round fails.

pub fn ordered(name: &str, f: impl Fn(&K) -> i8 + Send + Sync + 'static) -> Self

Create a group whose member priorities order one round rather than cut it off: every member with a non-negative priority is in the batch, best first.

The batch is benchmarked in that order and the short circuit ends it at the first candidate under the bounds’ time limit, so the priority decides how much of the group is compiled rather than which of it can win. The batch costs its whole membership without a bounds generator, on wasm, or with the short circuit disabled.

The batch sits at the priority of its best member, so a cutoff group at the same group priority interleaves with it by priority.
