Struct RetentionPolicy 

pub struct RetentionPolicy {
    pub keep_all_below: u128,
    pub hourly_below: u128,
    pub daily_below: u128,
    pub max_versions: usize,
    pub max_object_bytes: u64,
}

Controls the age windows used by thin_versions to decide which versions survive thinning.

All values are in milliseconds. The default matches the Time-Machine windows documented in this module’s top-level description.

Fields

keep_all_below: u128

Below this age, every version is kept (ms).

hourly_below: u128

Below this age, keep one per hour (ms).

daily_below: u128

Below this age, keep one per day (ms).

max_versions: usize

Maximum number of versions to retain (named versions and the latest are exempt from being dropped, but DO count toward the total).

max_object_bytes: u64

Maximum total compressed bytes of objects referenced by retained versions.

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 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.
