Struct RetentionConfig 

pub struct RetentionConfig {
    pub max_retained_versions: u32,
}

Retention configuration.

max_retained_versions is the total number of versions kept on disk, including current and rollback candidate.

max_retained_versions	Versions on disk
2 (default)	current + rollback candidate
3	current + rollback + 1 older
5	current + rollback + 3 older

Values below 2 are clamped to 2.

Config example

{ "max_retained_versions": 3 }

Fields

max_retained_versions: u32

Total number of versions to keep. Default 2, min 2.

Implementations

impl RetentionConfig

pub fn effective_max(&self) -> u32

Effective max, clamped to floor of 2.

Trait Implementations

impl Clone for RetentionConfig

fn clone(&self) -> RetentionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetentionConfig

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

Formats the value using the given formatter.

impl Default for RetentionConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetentionConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RetentionConfig

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

fn select_kept_sequences( &self, current_sequence: Option<u64>, rollback_candidate: Option<u64>, available_desc: &[HotswapMeta], ) -> HashSet<u64>

Return the set of sequence numbers to keep. The orchestrator will additionally preserve current + rollback candidate.

impl Serialize for RetentionConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
