Enum Scope 

pub enum Scope {
    Study(StudyId),
    Sampler(StudyId),
    Scheduler(StudyId),
    Trial(TrialId),
    Named(StudyId, String),
}

What a StateBlob belongs to.

Scoping is what keeps two samplers, a scheduler and user code from overwriting each other’s state without inventing key-prefix conventions.

Variants

Study(StudyId)

User-facing state attached to the study.

Sampler(StudyId)

The study’s sampler state (TPE’s history summaries, CMA-ES’s covariance, …).

Scheduler(StudyId)

The study’s scheduler state (ASHA rung tables, PBT populations, …).

Trial(TrialId)

State attached to a single trial (checkpoint references, artifacts).

Named(StudyId, String)

A caller-named slot inside a study.

Trait Implementations
