TinyBase

TinyBase is an in-memory database built with Rust, based on the sled embedded key-value store. It supports indexing and constraints, allowing you to create efficient queries and ensure data consistency.

Features

• In-memory storage for fast access.
• Built on top of sled for a reliable key-value store.
• Indexing support for efficient querying.
• Constraints to ensure data consistency.

Installation & Setup

To use TinyBase in your Rust project, add the following line to your Cargo.toml file's [dependencies] section:

toml tinybase = "0.1.1"

Usage Example

Here's a simple example demonstrating how to use TinyBase with a Person struct:

```rust

[derive(Serialize, Deserialize, Debug, Clone)]

struct Person { name: String, last_name: String, }

fn main() { let db = TinyBase::new(Some("./people"), true); let persontable: Table = db.opentable("people").unwrap();

let name_idx = person_table
    .create_index("name", |record| record.name.to_owned())
    .unwrap();

let lastname_idx = person_table
    .create_index("last_name", |record| record.last_name.to_owned())
    .unwrap();

person_table
    .constraint(Constraint::unique(&name_idx))
    .unwrap();

person_table
    .constraint(Constraint::check(|person| !person.name.contains(".")))
    .unwrap();

init_example_data(&person_table);

println!(
    "{:#?}",
    QueryBuilder::new(&person_table)
        .by(&name_idx, "John".to_string())
        .by(&lastname_idx, "Jones".to_string())
        .update(
            QueryOperator::Or,
            Person {
                name: "Kevin".to_string(),
                last_name: "Spacey".to_string()
            }
        )
        .unwrap()
);

}

fn initexampledata(persontable: &Table) { persontable .insert(Person { name: "John".tostring(), lastname: "Smith".to_string(), }) .unwrap();

person_table
    .insert(Person {
        name: "Bill".to_string(),
        last_name: "Smith".to_string(),
    })
    .unwrap();

person_table
    .insert(Person {
        name: "Coraline".to_string(),
        last_name: "Jones".to_string(),
    })
    .unwrap();

} ```

This example demonstrates how to create a new TinyBase instance, open a table (or create one if it doesn't exist), add indexes and constraints, and perform basic operations (insert/select).
