Struct GcRule 

#[non_exhaustive]
pub struct GcRule {
    pub rule: Option<Rule>,
    /* private fields */
}

Rule for determining which cells to delete during garbage collection.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rule: Option<Rule>

Garbage collection rules.

Implementations

impl GcRule

pub fn new() -> Self

pub fn set_rule<T: Into<Option<Rule>>>(self, v: T) -> Self

Sets the value of rule.

Note that all the setters affecting rule are mutually exclusive.

pub fn max_num_versions(&self) -> Option<&i32>

The value of rule if it holds a MaxNumVersions, None if the field is not set or holds a different branch.

pub fn set_max_num_versions<T: Into<i32>>(self, v: T) -> Self

Sets the value of rule to hold a MaxNumVersions.

Note that all the setters affecting rule are mutually exclusive.

pub fn max_age(&self) -> Option<&Box<Duration>>

The value of rule if it holds a MaxAge, None if the field is not set or holds a different branch.

pub fn set_max_age<T: Into<Box<Duration>>>(self, v: T) -> Self

Sets the value of rule to hold a MaxAge.

Note that all the setters affecting rule are mutually exclusive.

pub fn intersection(&self) -> Option<&Box<Intersection>>

The value of rule if it holds a Intersection, None if the field is not set or holds a different branch.

pub fn set_intersection<T: Into<Box<Intersection>>>(self, v: T) -> Self

Sets the value of rule to hold a Intersection.

Note that all the setters affecting rule are mutually exclusive.

pub fn union(&self) -> Option<&Box<Union>>

The value of rule if it holds a Union, None if the field is not set or holds a different branch.

pub fn set_union<T: Into<Box<Union>>>(self, v: T) -> Self

Sets the value of rule to hold a Union.

Note that all the setters affecting rule are mutually exclusive.

Trait Implementations

impl Clone for GcRule

fn clone(&self) -> GcRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GcRule

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

Formats the value using the given formatter.

impl Default for GcRule

fn default() -> GcRule

Returns the “default value” for a type.

impl Message for GcRule

fn typename() -> &'static str

The typename of this message.

impl PartialEq for GcRule

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