GlueSQL

SQL Database Engine as a Library

GlueSQL is a SQL database library written in Rust which provides parser (sqlparser-rs), execution layer, and an optional storage (sled).
Developers can use GlueSQL to build their own SQL databases or they can simply use GlueSQL as an embedded SQL database using default storage.

Standalone Mode

You can simply use GlueSQL as an embedded SQL database, GlueSQL provides sled as a default storage engine.

Installation

In your Cargo.toml toml [dependencies] gluesql = { version = "0.1.13", features = ["sled-storage"] }

Usage

```rust use gluesql::*;

fn main() { let storage = SledStorage::new("data.db").unwrap(); let mut glue = Glue::new(storage);

let sql = "
    CREATE TABLE Glue (id INTEGER);
    INSERT INTO Glue VALUES (100);
    INSERT INTO Glue VALUES (200);
    SELECT * FROM Glue WHERE id > 100;
    DROP TABLE Glue;
";

for query in parse(sqls).unwrap() {
    glue.execute(&query).unwrap();
}

} ```

SQL Library Mode (For Custom Storage)

Installation

Now you don't need to include sled-storage. So in Cargo.toml, toml [dependencies] gluesql = "0.1.13"

Usage

All you only need to do is implementing 2 traits: Store and StoreMut! In src/store.rs, ```rust pub trait Store { fn fetchschema(&self, tablename: &str) -> Result; fn scandata(&self, tablename: &str) -> Result>; }

pub trait StoreMut where Self: Sized { fn generateid(self, tablename: &str) -> MutResult; fn insertschema(self, schema: &Schema) -> MutResultschema(self, tablename: &str) -> MutResultdata(self, key: &T, row: Row) -> MutResult; fn delete_data(self, key: &T) -> MutResult
