Struct ClusterOwnershipDiagnostics 

#[non_exhaustive]
pub struct ClusterOwnershipDiagnostics {
    pub resolver: &'static str,
    pub resolutions: u64,
    pub no_owner: u64,
    pub stamp: u64,
}

Ownership diagnostics visible from a cluster control plane.

This is intentionally separate from ClusterDiagnostics so ownership counters can evolve without adding fields to the externally constructible runtime diagnostics snapshot.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

resolver: &'static str

Resolver name used by the control plane.

resolutions: u64

Number of ownership resolution attempts handled by this control plane.

no_owner: u64

Number of ownership resolutions that found no admitted member owner.

stamp: u64

Monotonic ownership table stamp for stale-view detection.

Implementations

impl ClusterOwnershipDiagnostics

pub fn new( resolver: &'static str, resolutions: u64, no_owner: u64, stamp: u64, ) -> Self

Create an ownership diagnostics snapshot.

pub fn owner_found(&self) -> u64

Number of ownership resolutions that selected an owner.

pub fn has_resolutions(&self) -> bool

Return whether any ownership resolution has been attempted.

pub fn owner_found_ratio(&self) -> Option<f64>

Ratio of ownership resolutions that found an admitted owner.

Trait Implementations

impl Clone for ClusterOwnershipDiagnostics

fn clone(&self) -> ClusterOwnershipDiagnostics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClusterOwnershipDiagnostics

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

Formats the value using the given formatter.

impl Deserialize<'static> for ClusterOwnershipDiagnostics

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

where __D: Deserializer<'static>,

Deserialize this value from the given Serde deserializer.

impl Eq for ClusterOwnershipDiagnostics

impl PartialEq for ClusterOwnershipDiagnostics

fn eq(&self, other: &ClusterOwnershipDiagnostics) -> 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 ClusterOwnershipDiagnostics

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
