💅 MQTTClient_persistence(3) — like, the manual page bestie

okay so real talk, this one lives in the Library Functions Manual section (that's the 3 in MQTTClient_persistence(3), iykyk) 💖

✨ NAME ✨

MQTTClient_persistence — a struct holding the function pointers for a persistence implementation, plus the context / state that gets shared across all the persistence functions 🫶

🌸 SYNOPSIS 🌸

#include <MQTTClientPersistence.h>

🎀 Data Fields

void * context
Persistence_open popen
Persistence_close pclose
Persistence_put pput
Persistence_get pget
Persistence_remove premove
Persistence_keys pkeys
Persistence_clear pclear
Persistence_containskey pcontainskey

🦋 DESCRIPTION 🦋

It's giving... a structure containing the function pointers to a persistence implementation, and the context or state that will be shared across all the persistence functions. periodt. ✨

No cap, that's the whole vibe of this struct: it's the little bundle that says "here's how you save stuff, here's how you load it back, and here's the state we all pass around." 👑

💖 Field Documentation 💖

void* context

A pointer to any data required to initialize the persistent store. literally whatever your implementation needs, bestie. 🌈

Persistence_open popen

A function pointer to an implementation of Persistence_open(). 🔥

Persistence_close pclose

A function pointer to an implementation of Persistence_close(). 🔥

Persistence_put pput

A function pointer to an implementation of Persistence_put(). 🔥

Persistence_get pget

A function pointer to an implementation of Persistence_get(). 🔥

Persistence_remove premove

Persistence_keys pkeys

A function pointer to an implementation of Persistence_keys(). 🔥

Persistence_clear pclear

A function pointer to an implementation of Persistence_clear(). 🔥

Persistence_containskey pcontainskey

A function pointer to an implementation of Persistence_containskey(). 🔥

💀 not a single option flag in sight — this one's a struct, not a command, so no flags to memorize. you're welcome, bestie.
