Generic preferences storage with scope/namespace/key design

What it is for

infrastructure-preferences: Generic preferences storage

Overview

This crate provides a preferences storage system with scope/namespace/key design. Preferences are stored in Postgres with JSONB values for flexibility.

Key Types

• PreferenceScope - Who owns the preference (user, tenant, org)
• PreferenceKey - Fully qualified preference key
• PreferencesService - Get/set/delete operations

Example

use infrastructure_preferences::{PreferenceKey, PreferencesService};

let service = PreferencesService::new(pool);
let key = PreferenceKey::user(user_id, "support-web", "theme");

// Set a preference
service.set(&key, &"dark").await?;

// Get a preference
let theme: Option<String> = service.get(&key).await?;

// Get with default
let theme: String = service.get_or_default(&key).await?;

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

No public items.

Re-exports. Exported here, defined elsewhere.

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.
