Stdlib.Ephemeron(3)

💖 Stdlib.Ephemeron(3) — OCaml library, bestie 💖

okay so welcome to the Stdlib.Ephemeron(3) page from the OCaml library — we're doing this, and we're doing it cute ✨

---

🌸 NAME 🌸

Stdlib.Ephemeron — no description. That's it. That's the whole description. The manpage said "no description" and honestly? Iconic minimalism 😭💅

🎀 Module 🎀

The module moment is exactly:

Module   Stdlib.Ephemeron

✨ Documentation ✨

The docs start with:

Module Ephemeron
 : (module Stdlib__Ephemeron)

💅 Unsynchronized accesses 💅

Okay bestie, this is the caution part, so listen up 🫶: unsynchronized accesses to a weak hash table may lead to an invalid weak hash table state. Thus, concurrent accesses to a weak hash table must be synchronized — for instance with a Mutex.t. No cap, that's the rule. 🔥

🦋 module type S = sig end 🦋

module type S = sig end

This is the output signature of the functors Ephemeron.K1.Make and Ephemeron.K2.Make.

These hash tables are weak in the keys. If all the keys of a binding are alive the binding is kept, but if one of the keys of the binding is dead then the binding is removed. periodt 💅

🌈 module type SeededS = sig end 🌈

module type SeededS = sig end

This one is the output signature of the functors Ephemeron.K1.MakeSeeded and Ephemeron.K2.MakeSeeded. seeded bestie behavior ✨

🧚 module K1 : sig end 🧚

module K1 : sig end

Ephemerons with one key. solo-key main character energy 👑

🍓 module K2 : sig end 🍓

module K2 : sig end

Ephemerons with two keys. duo vibes, lowkey cute 🫶

⭐ module Kn : sig end ⭐

module Kn : sig end

Ephemerons with arbitrary number of keys of the same type. not me loving the flexible icon behavior 🌈
