Struct CompactionPolicy 

pub struct CompactionPolicy {
    pub max_age_days: Option<u64>,
    pub max_entries_per_key: Option<usize>,
    pub strategy: CompactionStrategy,
}

Policy for memory retention and compaction.

Fields

max_age_days: Option<u64>

max_entries_per_key: Option<usize>

strategy: CompactionStrategy

Implementations

impl CompactionPolicy

pub fn delete_older_than(days: u64) -> Self

pub fn keep_recent(per_key: usize) -> Self

pub fn compact(&self, entries: &[MemoryEntry]) -> CompactionResult

Apply compaction to a list of memory entries, returning retained entries and the count of compacted entries.

Trait Implementations

impl Clone for CompactionPolicy

fn clone(&self) -> CompactionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompactionPolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompactionPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CompactionPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
