A powerful schema migration builder for Rust. Write complicated SQL schema migrations in Rust and easily switch databases.
`barrel` is meant to make writing migrations for different databases as easy as possible. It creates a simple to use API over SQL which allows you to focus on managing your database, not fighting with SQL.
## Example
`barrel` currently requires the nightly compiler. The following code is a simple example of how to get started
```rust
extern crate barrel;
use barrel::*;
use barrel::backend::Pg;
fn main() {
let mut m = Migration::new();
m.create_table("users", |t| {
t.add_column("name", Type::Text);
t.add_column("age", Type::Integer);
t.add_column("owns_plushy_sharks", Type::Boolean);
});
println!("{}", m.make::<Pg>());
}
```
If you have feedback [regarding the API](https://github.com/spacekookie/barrel/issues/1) or things you would want barrel to do, please open an issue. And documentation PR's are always welcome 💚
