Enum Rule 

#[non_exhaustive]
pub enum Rule {
    MaxNumVersions(i32),
    MaxAge(Box<Duration>),
    Intersection(Box<Intersection>),
    Union(Box<Union>),
}

Garbage collection rules.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MaxNumVersions(i32)

Delete all cells in a column except the most recent N.

MaxAge(Box<Duration>)

Delete cells in a column older than the given age. Values must be at least one millisecond, and will be truncated to microsecond granularity.

Intersection(Box<Intersection>)

Delete cells that would be deleted by every nested rule.

Union(Box<Union>)

Delete cells that would be deleted by any nested rule.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rule

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

Formats the value using the given formatter.

impl PartialEq for Rule

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