rust_dependencies

Typed dependency injection for Rust

Register values by type, swap live vs test implementations, and override individual deps without global state.

Install

[dependencies]
rust_dependencies = "0.1.2"

Quick start

use rust_dependencies::{DependencyKey, DependencyValues, UuidDep};

let bag = DependencyValues::test();
let uuid = bag.require::<UuidDep>().unwrap().0.next();
assert_ne!(uuid, 0);

Built-in dependencies

Key	Purpose
`ClockKey`	Monotonic `Instant` (debounce, elapsed time)
`NowKey`	Wall `SystemTime` (timestamps)
`UuidKey`	Unique `u128` identifiers
`RngKey`	`u64` random draws

Each key provides live() (production) and test() (deterministic) via [DependencyKey].
