pub struct QueryHealth<ChildId> { /* private fields */ }

Health metadata for a distributed query result.

Implementations

impl<ChildId> QueryHealth<ChildId>

pub fn new() -> Self

Creates empty health metadata.

pub fn with_expected_children(expected_children: usize) -> Self

Creates health metadata with an expected child count.

pub fn expected_children(&self) -> usize

Returns the expected child count.

pub fn completed_children(&self) -> usize

Returns the completed child count.

pub fn issues(&self) -> &[ChildIssue<ChildId>]

Returns all recorded issues.

pub fn record_completed(&mut self)

Records a completed child response.

pub fn record_issue(&mut self, issue: ChildIssue<ChildId>)

Records an issue.

pub fn push_issue( &mut self, child: ChildId, kind: IssueKind, detail: impl Into<String>, )

Records an issue by parts.

pub fn is_partial(&self) -> bool

Returns true if any issue has been recorded or some expected children did not complete.

pub fn completeness(&self) -> f64

Returns the completed-child ratio in 0.0..=1.0.

Trait Implementations

fn clone(&self) -> QueryHealth<ChildId>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl<ChildId> Default for QueryHealth<ChildId>

fn default() -> Self

Returns the “default value” for a type.

impl<ChildId: PartialEq> PartialEq for QueryHealth<ChildId>

fn eq(&self, other: &QueryHealth<ChildId>) -> 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.
