Invocation Control Toolkit

A small utility module for controlling how often functions execute and how results are reused.

Capabilities

Each factory returns a wrapper around the supplied function that enforces the described invocation rules.

Search request coalescer

• Rapid calls within the quiet period trigger only one underlying fetch using the most recent query, executed after no calls occur for the full quiet period. @test

Notification windowing

• The first call within any window executes immediately, further calls within the window do not trigger the notifier, and the next call after the window executes with that call's payload. @test

Single-run initializer

• The initialization routine executes at most once and all wrapper invocations return the first result without rerunning initialization. @test

Memoized score lookup

• Results are cached per derived key so repeated calls with the same key reuse cached values while distinct keys compute independently. @test

Implementation

API
