Struct TrialTemplate 

pub struct TrialTemplate {
    pub fixed: Assignment,
    pub parent: Option<TrialId>,
}

A request to create a trial with something already decided.

Covers two cases:

• enqueued trials: fixed parameters the user wants evaluated, which take priority over sampling (what a trial’s parameters actually are);
• forks: a child of parent, used by PBT-style schedulers in M4. Storage persists the reference onto FrozenTrial::parent; M1 does nothing else with it.

Fields

fixed: Assignment

Parameters that must not be sampled.

parent: Option<TrialId>

The trial this one forks from, if any.

Implementations

impl TrialTemplate

pub fn fixed(params: Assignment) -> Self

A template with fixed parameters and no parent.

pub fn fork(parent: TrialId, mutation: Assignment) -> Self

A template that forks parent, carrying mutated parameters.

pub fn is_empty(&self) -> bool

true if nothing is fixed and there is no parent.
