Struct Pool

pub struct Pool { /* private fields */ }

A simple Pool of sqlite connections.

A Pool has the same API as an individual Client.

Implementations

impl Pool

pub async fn conn<F, T>(&self, func: F) -> Result<T, Error>

where F: FnOnce(&Connection) -> Result<T, Error> + Send + 'static, T: Send + 'static,

Invokes the provided function with a rusqlite::Connection.

pub async fn conn_with_err<F, T, E: From<Error> + From<Error> + Send + 'static>( &self, func: F, ) -> Result<T, E>

where F: FnOnce(&Connection) -> Result<T, E> + Send + 'static, T: Send + 'static,

Invokes the provided function with a rusqlite::Connection.

pub async fn conn_mut<F, T>(&self, func: F) -> Result<T, Error>

where F: FnOnce(&mut Connection) -> Result<T, Error> + Send + 'static, T: Send + 'static,

Invokes the provided function with a mutable rusqlite::Connection.

pub async fn conn_mut_with_err<F, T, E: From<Error> + From<Error> + Send + 'static>( &self, func: F, ) -> Result<T, E>

where F: FnOnce(&mut Connection) -> Result<T, E> + Send + 'static, T: Send + 'static,

Invokes the provided function with a mutable rusqlite::Connection.

pub async fn transaction_write<F, T, E: From<Error> + From<Error> + Send + 'static>( &self, func: F, ) -> Result<T, E>

where F: FnOnce(&mut Transaction<'_>) -> Result<T, E> + Send + 'static, T: Send + 'static,

Invokes the provided function wrapping a new rusqlite::Transaction that is committed automatically.

pub async fn transaction_read<F, T, E: From<Error> + From<Error> + Send + 'static>( &self, func: F, ) -> Result<T, E>

where F: FnOnce(&mut Transaction<'_>) -> Result<T, E> + Send + 'static, T: Send + 'static,

Invokes the provided function wrapping a new rusqlite::Transaction that is committed automatically.

pub async fn close(&self) -> Result<(), Error>

Closes the underlying sqlite connections.

After this method returns, all calls to self::conn() or self::conn_mut() will return an Error::Closed error.

pub fn conn_blocking<F, T>(&self, func: F) -> Result<T, Error>

where F: FnOnce(&Connection) -> Result<T, Error> + Send + 'static, T: Send + 'static,

Invokes the provided function with a rusqlite::Connection, blocking the current thread.

pub fn conn_mut_blocking<F, T>(&self, func: F) -> Result<T, Error>

where F: FnOnce(&mut Connection) -> Result<T, Error> + Send + 'static, T: Send + 'static,

Invokes the provided function with a mutable rusqlite::Connection, blocking the current thread.

pub fn close_blocking(&self) -> Result<(), Error>

Closes the underlying sqlite connections, blocking the current thread.

After this method returns, all calls to self::conn_blocking() or self::conn_mut_blocking() will return an Error::Closed error.

Trait Implementations

impl Clone for Pool

fn clone(&self) -> Pool

Returns a duplicate of the value.

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

Performs copy-assignment from source.
