Struct Database 

pub struct Database { /* private fields */ }

The main entry point for database connection and management.

It handles connection pooling, driver detection, and schema operations.

Implementations

impl Database

pub async fn connect(url: &str) -> Result<Self, Error>

Connects to the database using a connection string (Database URL).

It automatically identifies the driver (Postgres, MySQL, SQLite) based on the URL prefix.

Arguments

• url - The database connection string (e.g., postgres://user:pass@localhost/db).

Example

let db = Database::connect("postgres://user:password@localhost/mydb").await?;

pub fn migrator(&self) -> Migrator<'_>

Creates a Migrator instance to manage schema migrations.

pub fn model<T: Model + Send + Sync + Unpin>(&self) -> QueryBuilder<'_, T>

Starts building a query for a specific Model.

Example

let query = db.model::<User>();

pub async fn create_table<T: Model>(&self) -> Result<&Self, Error>

Creates the table for model T if it does not exist.

This method generates SQL for columns, primary keys, indexes, and constraints.

pub async fn assign_foreign_keys<T: Model>(&self) -> Result<&Self, Error>

Checks for and assigns Foreign Keys for model T.

This function verifies if the constraint already exists before attempting to create it to avoid duplication errors.

Trait Implementations

impl Clone for Database

fn clone(&self) -> Database

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
