Struct BanditCache

pub struct BanditCache { /* private fields */ }

Implementations

impl BanditCache

pub fn new() -> Self

Creates a new, empty BanditCache.

The cache is initialized as an empty HashMap and is used to store precomputed Beta distribution parameters for faster access during Thompson Sampling operations.

pub fn get_beta_distribution( &mut self, bandit: &str, arm: &str, db: &RelevancyDb, ) -> Result<(u64, u64)>

Retrieves the Beta distribution parameters for a given bandit and arm.

If the parameters for the specified bandit and arm are already cached, they are returned directly. Otherwise, the parameters are fetched from the database, added to the cache, and then returned.

pub fn clear(&mut self, bandit: &str, arm: &str)

Clears the cached Beta distribution parameters for a given bandit and arm.

This removes the cached values for the specified bandit and arm from the cache. Use this method if the cached parameters are no longer valid or need to be refreshed.
