Crate typesafe_repository

Expand description

typesafe_repository is designed to abstract data persistence, so its implementations can be easily swapped for testing or migration purposes

You can create your own repository by implementing traits like Add, List, Get, and plenty of others (see async_ops for complete list)

Typical way to define abstract repository for some type is:

use typesafe_repository::{Identity, Repository, Add, List, Remove};
use typesafe_repository::inmemory::InMemoryRepository;
use typesafe_repository::macros::Id;
use std::sync::Arc;

#[derive(Clone, Id)]
pub struct Foo {
  id: usize,
}

trait FooRepository:
  Repository<Foo, Error = Box<dyn std::error::Error + Send + Sync>>
  + Add<Foo>
  + List<Foo>
  + Remove<Foo>
{}

impl<T> FooRepository for T
where T: Repository<Foo, Error = Box<dyn std::error::Error + Send + Sync>>
    + Add<Foo>
    + List<Foo>
    + Remove<Foo> {}

struct FooService {
  repo: Arc<dyn FooRepository>,
}

// You can mock any repository with InMemoryRepository since it implements all operations on
// all types
let repo = Arc::new(InMemoryRepository::new());
FooService { repo };
