Enum QuotaReductionPolicy 

#[non_exhaustive]
pub enum QuotaReductionPolicy {
    Reject,
    GrandfatherExisting,
    ThrottleProportional,
}

What to do when a parent’s quota reduction would drop below the aggregate usage of its children. Default: Reject.

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.

Reject

Reject the reduction request if new_quota < sum(child_usage).

GrandfatherExisting

Existing usage retained as-is; the new quota applies only to future allocations.

ThrottleProportional

Existing usage proportionally scaled down; deterministic round-robin over BTreeMap<InstanceId, _> ascending order distributes any remainder bytes.

Trait Implementations

impl Clone for QuotaReductionPolicy

fn clone(&self) -> QuotaReductionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuotaReductionPolicy

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

Formats the value using the given formatter.

impl Default for QuotaReductionPolicy

fn default() -> QuotaReductionPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QuotaReductionPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QuotaReductionPolicy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
