# Take home assignment

This library provides generic implementation of `Cache[T]` which can be accessed concurrently and is guaranteed to make at most

one call to underlying data source for any given key.

To function correctly this cache requires `DataSource[T]` that implements `Get(key string) (*T, error)`.

## How to run tests

Tests can be run either with `go test . -race` or if nix is installed `nix develop . -c bash -c "go test . -race"`. Second approach would

automatically install and use pinned Go version.

### Things to note

- tests can be a little flaky for huge amounts of concurrent requests (as far as I'm aware that's because of machine running out of RAM)

- this library caches keys indefinitely right now, but it's quite easy to add cache invalidation scheme
