Toasty supports SQL databases (SQLite/Turso, PostgreSQL, MySQL) and DynamoDB. It does not hide database capabilities — it exposes features based on the target database.

You will define your data model using Rust structs annotated with the #[derive(toasty::Model)] derive macro. Runnable examples live in the examples/ directory; the snippets below illustrate the basics.

Toasty supports both SQL and NoSQL databases. Current drivers are SQLite, Turso, PostgreSQL, MySQL, and DynamoDB. However, it does not aim to abstract the database. Instead, Toasty leans into the target database's capabilities and aims to help the user avoid issuing inefficient queries for that database.

When targeting both SQL and NoSQL databases, Toasty generates query methods (e.g. get_by_id only for access patterns that are indexed). When targeting a SQL database, Toasty might allow arbitrary additional query constraints. When targeting a NoSQL database, Toasty will only allow constraints that the specific target database can execute. For example, with DynamoDB, query methods might be generated based on the table's primary key, and additional constraints may be set for the sort key.
