Struct MemoryStorage 

pub struct MemoryStorage<V> { /* private fields */ }

In-memory trial storage (the default).

Wrap a Vec<CompletedTrial<V>> behind a read-write lock so that trials can be appended from any thread. This is the backend that Study uses when no explicit storage is provided.

Use with_trials to seed a study with previously collected data.

Example

use optimizer::storage::{MemoryStorage, Storage};

let storage = MemoryStorage::<f64>::new();
assert_eq!(storage.trials_arc().read().len(), 0);

Implementations

impl<V> MemoryStorage<V>

pub fn new() -> Self

Create a new, empty in-memory store.

pub fn with_trials(trials: Vec<CompletedTrial<V>>) -> Self

Create an in-memory store pre-populated with trials.

The internal ID counter is set to one past the highest trial ID so that subsequent trials receive unique IDs.

Trait Implementations

impl<V> Default for MemoryStorage<V>

fn default() -> Self

Returns the “default value” for a type.

impl<V: Send + Sync> Storage<V> for MemoryStorage<V>

fn push(&self, trial: CompletedTrial<V>)

Append a completed trial to the store.

fn trials_arc(&self) -> &Arc<RwLock<Vec<CompletedTrial<V>>>>

Return a reference to the in-memory trial buffer.

fn next_trial_id(&self) -> u64

Atomically return the next unique trial ID.

fn peek_next_trial_id(&self) -> u64

Return the current value of the next-trial-ID counter without incrementing.

fn refresh(&self) -> bool

Reload from an external source (e.g. a file written by another process). Return true if the in-memory buffer was updated.
