Struct holochain_types::db_cache::DhtDbQueryCache

source · [−]

pub struct DhtDbQueryCache { /* private fields */ }

Expand description

This cache allows us to track selected database queries that are too slow to run frequently. The queries are lazily evaluated and cached. Then the cache is updated in memory without needing to go to the database.

Implementations

source

impl DhtDbQueryCache

source

pub async fn get_state(
&self
) -> &RwShare<HashMap<Arc<AgentPubKey>, ActivityState>>

Get the caches internal state for testing.

source

impl DhtDbQueryCache

source

pub fn new(dht_db: DbRead<DbKindDht>) -> Self

Create a new cache for dht database queries.

source

pub async fn get_activity_to_integrate(
&self
) -> DatabaseResult<Vec<(Arc<AgentPubKey>, RangeInclusive<u32>)>>

Get any activity that is ready to be integrated. This returns a range of activity that is ready to be integrated for each agent.

source

pub async fn is_chain_empty(&self, author: &AgentPubKey) -> DatabaseResult<bool>

Is the SourceChain empty for this AgentPubKey?

source

pub async fn set_all_activity_to_integrated(
&self,
integrated_activity: Vec<(Arc<AgentPubKey>, RangeInclusive<u32>)>
) -> DbCacheResult<()>

Mark agent activity as actually integrated.

source

pub async fn set_activity_ready_to_integrate(
 &self,
 agent: &AgentPubKey,
 header_sequence: u32
) -> DbCacheResult<()>

Set activity to ready to integrate.

source

pub async fn set_activity_to_integrated(
 &self,
 agent: &AgentPubKey,
 header_sequence: u32
) -> DbCacheResult<()>

Set activity to to integrated.
