mock_instant

mock_instant

This crate allows you to test Instant/Duration code, deterministically per thread.

If cross-thread determinism is required, enable the sync feature:

toml mock_instant = { version = "0.2", features = ["sync"] }

It provides a replacement std::time::Instant that uses a deterministic thread-local 'clock'

You can swap out the std::time::Instant with this one by doing something similar to:

```rust

[cfg(test)]

use mock_instant::Instant;

[cfg(not(test))]

use std::time::Instant; ```

Example

```rust use std::time::Duration;

let now = Instant::now(); MockClock::advance(Duration::fromsecs(15)); MockClock::advance(Duration::fromsecs(2));

// its been '17' seconds asserteq!(now.elapsed(), Duration::fromsecs(17)); ```
