Struct Pool 

pub struct Pool<DB: Database> { /* private fields */ }

A connection pool wrapping sqlx::Pool.

Generic over DB: sqlx::Database so that the same API works with SQLite, PostgreSQL, and MySQL while retaining compile-time type safety.

Implementations

impl<DB: Database> Pool<DB>

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

Connect to the database at the given URL.

This creates a connection pool with SQLx’s default pool options.

pub fn builder() -> PoolBuilder<DB>

Returns a PoolBuilder for configuring pool options before connecting.

pub async fn close(&self)

Close the pool, waiting for all connections to be returned.

pub fn inner(&self) -> &Pool<DB>

Returns a reference to the underlying sqlx pool.

Escape hatch for advanced or raw SQLx access. Prefer fletch CRUD and the query builder where possible.

pub fn size(&self) -> u32

Returns the number of connections currently active (including idle).

pub fn num_idle(&self) -> usize

Returns the number of idle connections in the pool.

pub async fn begin(&self) -> Result<Transaction<'static, DB>, FletchError>

Begin a new transaction.

Trait Implementations

impl<DB: Database> Clone for Pool<DB>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<DB: Debug + Database> Debug for Pool<DB>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
