pub struct PolicyCache { /* private fields */ }

A thread-safe cache for storing policies by their associated public keys.

Implementations

impl PolicyCache

pub fn new() -> Self

Creates a new, empty PolicyCache.

Returns

A new instance of PolicyCache with an empty internal storage.

pub fn insert(&self, pubkey: Pubkey, slot: u64, item: Policy)

Inserts a policy into the cache, associating it with the given public key. Only updates if the incoming slot is greater than the current slot.

Arguments

• pubkey - The public key to associate with the policy.
• slot - The slot number of the policy update.
• policy - The policy to be stored in the cache.

pub fn get(&self, pubkey: &Pubkey) -> Option<Policy>

Retrieves a policy from the cache associated with the given public key.

Arguments

• pubkey - The public key whose associated policy is to be retrieved.

Returns

An Option containing a reference to the policy if found, or None if no policy is associated with the given public key.

pub fn remove(&self, pubkey: &Pubkey) -> Option<()>

Removes a policy from the cache associated with the given public key.

Arguments

• pubkey - The public key whose associated policy is to be removed.

Returns

Some(()) if a policy was removed, or None if no policy was associated with the given public key.

pub fn all(&self) -> Vec<(Pubkey, Policy)>

Retrieves all policies currently stored in the cache.

Returns

A vector of tuples where each tuple contains a reference to a public key and its associated policy.
