    },
}

Retention policy for managing MVCC version cleanup

Variants

KeepForever

KeepVersions

Keep only the last N versions

Fields

count: u64

cleanup_mode: CleanupMode

Implementations

impl RetentionPolicy

pub fn should_retain( &self, _version: CommitVersion, _current_version: CommitVersion, version_count: u64, ) -> bool

Check if a version should be retained based on the policy

pub fn cleanup_mode(&self) -> Option<CleanupMode>

Get the cleanup mode for this policy

Trait Implementations

impl Clone for RetentionPolicy

fn clone(&self) -> RetentionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetentionPolicy

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

Formats the value using the given formatter.

impl Default for RetentionPolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetentionPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RetentionPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
