    pub query_region: RegionMapping,
    pub timestamps_region: RegionMapping,
}

Query cache region contract.

Fields

Implementations

impl QueryCacheMapping

pub fn new( query_region: RegionMapping, timestamps_region: RegionMapping, ) -> Result<Self, ClientProtocolError>

Build a query-cache mapping that uses timestamp/bulk invalidation.

pub fn bulk_update_evictions(&self) -> [ClientRequest; 2]

Build the two W1 evictions needed after a bulk update.

Trait Implementations

impl Clone for QueryCacheMapping

fn clone(&self) -> QueryCacheMapping

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryCacheMapping

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueryCacheMapping

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for QueryCacheMapping

impl PartialEq for QueryCacheMapping

fn eq(&self, other: &QueryCacheMapping) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for QueryCacheMapping

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
