Cooldown Algorithms API Reference#

class lightbulb.cooldown_algorithms.BangBangCooldownAlgorithm[source]#

Cooldown algorithm that allows n command invocations to be used, and then waits for the appropriate amount of time before allowing any additional invocations.

evaluate(bucket: buckets.Bucket) → CooldownStatus[source]#

Evaluate whether the command should be on cooldown given internal state of this object and the bucket object passed in.

Parameters:: bucket (Bucket) – The bucket to process the cooldown for.
Returns:: The status of the cooldown.
Return type:: CooldownStatus

class lightbulb.cooldown_algorithms.CooldownAlgorithm[source]#

Base class that represents an algorithm that can be used to calculate whether a command is on cooldown or not.

abstract evaluate(bucket: buckets.Bucket) → t.Union[CooldownStatus, t.Coroutine[t.Any, t.Any, CooldownStatus]][source]#

Evaluate whether the command should be on cooldown given internal state of this object and the bucket object passed in.

Parameters:: bucket (Bucket) – The bucket to process the cooldown for.
Returns:: The status of the cooldown.
Return type:: CooldownStatus

class lightbulb.cooldown_algorithms.CooldownStatus(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)[source]#

class lightbulb.cooldown_algorithms.FixedWindowCooldownAlgorithm[source]#

Cooldown algorithm that allows n command invocations within a fixed window time period. I.e. 5 invocations within a 30-second time period, allowing additional invocations once the entire period has elapsed.

evaluate(bucket: buckets.Bucket) → CooldownStatus[source]#

Evaluate whether the command should be on cooldown given internal state of this object and the bucket object passed in.

Parameters:: bucket (Bucket) – The bucket to process the cooldown for.
Returns:: The status of the cooldown.
Return type:: CooldownStatus

class lightbulb.cooldown_algorithms.SlidingWindowCooldownAlgorithm[source]#

Cooldown algorithm that allows n command invocations within a sliding window time period. I.e. 5 invocations within the last 30 seconds will allow an extra invocation every time the earliest invocation falls out of the window.

evaluate(bucket: buckets.Bucket) → CooldownStatus[source]#

Evaluate whether the command should be on cooldown given internal state of this object and the bucket object passed in.

Parameters:: bucket (Bucket) – The bucket to process the cooldown for.
Returns:: The status of the cooldown.
Return type:: CooldownStatus
