This is a WIP rust query builder.
WIP means that it is probably not yet suitable for your project, but you can try it out and give me feedback.
The idea is to have a deep embedding, this means that we reuse rust concepts for queries:
- Query ~ Function
- Column ~ Variable
- Scope ~ Lifetime
- Query phase ~ Mutability
Using the full expressiveness of the rust type system like this allows us to write queries that can not fail at runtime and get (nice) error messages.
Current limitations
This is a WIP project and thus has a number of limitations.
- Only support for select and insert statements.
- Very small number of operators.
- No support for window functions.
- Etc.
Despite these limitations, I am dogfooding this query builder and using it in my own project: advent-of-wasm.
Practice/Tutorial
First download the Chinook_Sqlite.sql
from here https://github.com/lerocha/chinook-database/releases and put it in the chinook
folder.
Then you can run with cd chinook
&& cargo run
There are some queries there that you can implement to test out the query builder.
