[][src]Enum ratelimit_meter::NegativeMultiDecision

pub enum NegativeMultiDecision<E: Fail> {
    BatchNonConforming(u32, E),
    InsufficientCapacity(u32),
}

Gives additional information about the negative outcome of a batch cell decision.

Since batch queries can be made for batch sizes bigger than the rate limiter parameter could accomodate, there are now two possible negative outcomes:

  • BatchNonConforming - the query is valid but the Decider can not accomodate them.

  • InsufficientCapacity - the query was invalid as the rate limite parameters can never accomodate the number of cells queried for.

Variants

A batch of cells (the first argument) is non-conforming and can not be let through at this time. The second argument gives information about when that batch of cells might be let through again (not accounting for thundering herds and other, simultaneous decisions).

The number of cells tested (the first argument) is larger than the bucket's capacity, which means the decision can never have a conforming result.
