Enum RetentionRule 

pub enum RetentionRule {
    KeepFrameKind(FrameKind),
    KeepScope(Scope),
    KeepRecent {
        min_sequence: u64,
    },
    DropWrittenBefore {
        older_than_unix_ms: u64,
    },
    DropLastAccessedBefore {
        older_than_unix_ms: u64,
    },
    DropOutsideScope {
        required_scope: Option<Scope>,
    },
    KeepLabel(String),
    DropLabel(String),
}

One deterministic retention rule.

Variants

KeepFrameKind(FrameKind)

Keep candidates whose frame kind matches kind.

KeepScope(Scope)

Keep candidates whose normalized scope exactly matches this scope.

KeepRecent

Keep candidates at or above min_sequence, where larger sequence values are newer.

Fields

min_sequence: u64

Minimum sequence number to keep, where larger sequence values are newer.

DropWrittenBefore

Drop candidates whose write timestamp is older than older_than_unix_ms.

Fields

older_than_unix_ms: u64

Exclusive Unix-millisecond threshold; candidates written before this value are dropped.

DropLastAccessedBefore

Drop candidates whose last-access timestamp is older than older_than_unix_ms.

Fields

older_than_unix_ms: u64

Exclusive Unix-millisecond threshold; candidates last accessed before this value are dropped.

DropOutsideScope

Drop candidates whose normalized scope does not exactly match required_scope. None requires an unscoped candidate.

Fields

required_scope: Option<Scope>

Required exact scope. None requires candidates to be unscoped.

KeepLabel(String)

Keep candidates with a host-defined retention label.

DropLabel(String)

Drop candidates with a host-defined retention label.

Implementations

impl RetentionRule

pub fn evaluate(&self, candidate: RetentionCandidate<'_>) -> RetentionDecision

Evaluate this rule against a single candidate.

Trait Implementations

impl Clone for RetentionRule

fn clone(&self) -> RetentionRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetentionRule

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

Formats the value using the given formatter.

impl PartialEq for RetentionRule

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