Struct ClusterPeerFetchRequest 

pub struct ClusterPeerFetchRequest {
    pub owner: ClusterNodeId,
    pub key: String,
    pub generation: Option<ClusterGeneration>,
}

Fields

owner: ClusterNodeId

Owner member expected to serve this request.

key: String

Logical cache key requested from the owner.

generation: Option<ClusterGeneration>

Optional owner generation observed by the caller.

Implementations

impl ClusterPeerFetchRequest

pub fn new(owner: impl Into<ClusterNodeId>, key: impl Into<String>) -> Self

Create a new peer-fetch request.

pub fn generation(self, generation: ClusterGeneration) -> Self

Attach the owner generation observed by the caller.

pub fn has_generation(&self) -> bool

Return whether this request carries an observed owner generation.

pub fn matches_generation(&self, current: ClusterGeneration) -> bool

Return whether this request can be served by current owner generation.

pub fn generation_mismatch( &self, current: ClusterGeneration, ) -> Option<ClusterPeerFetchGenerationMismatch>

Return mismatch details when the observed owner generation is stale.

Trait Implementations

impl Clone for ClusterPeerFetchRequest

fn clone(&self) -> ClusterPeerFetchRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClusterPeerFetchRequest

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

Formats the value using the given formatter.

impl Eq for ClusterPeerFetchRequest

impl PartialEq for ClusterPeerFetchRequest

fn eq(&self, other: &ClusterPeerFetchRequest) -> 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.
