postgres-es

A Postgres implementation of the EventStore trait in cqrs-es.

Usage

Add to your Cargo.toml file:

[dependencies]
cqrs-es = "0.2.3"
persist-es = "0.2.3"
postgres-es = "0.2.3"

Requires access to a Postgres DB with existing tables. See:

• Sample database configuration
• Use docker-compose to quickly setup a local database

A simple configuration example:

let store = default_postgress_pool("postgresql://my_user:my_pass@localhost:5432/my_db");
let cqrs = postgres_es::postgres_cqrs(pool, vec![])
