Struct StudyBuilder 

pub struct StudyBuilder { /* private fields */ }

Fluent builder for a Study, with sensible defaults: a RandomSampler, a NopPruner, an InMemoryStorage, and Direction::Minimize. Override any of them before calling StudyBuilder::build.

Implementations

impl StudyBuilder

pub fn new(name: impl Into<String>) -> Self

Start building a study with the given name.

pub fn direction(self, direction: Direction) -> Self

Set the optimization direction (default Direction::Minimize).

pub fn sampler(self, sampler: impl Sampler + 'static) -> Self

Set the search algorithm (default RandomSampler).

pub fn pruner(self, pruner: impl Pruner + 'static) -> Self

Set the early-stopping policy (default NopPruner).

pub fn storage(self, storage: impl Storage + 'static) -> Self

Set the storage backend (default InMemoryStorage).

pub fn build(self) -> Result<Study, HyperoptError>

Assemble the Study, applying defaults for anything not set.
