Struct reool::node_pool::SingleNodePool

pub struct SingleNodePool { /* fields omitted */ }

A connection pool that maintains multiple connections to a single Redis instance.

The pool is cloneable and all clones share their connections. Once the last instance drops the shared connections will be dropped.

Methods

impl SingleNodePool

pub fn builder() -> Builder<(), ()>

Creates a builder for a SingleNodePool

pub fn new<T>(
    config: Config,
    connect_to: T
) -> Result<Self, InitializationError> where
    T: IntoConnectionInfo, 

Creates a new instance of a SingleNodePool.

This function must be called on a thread of the tokio runtime.

pub fn add_connections(&self, n: usize)

Add n new connections to the pool.

This might not happen immediately.

pub fn remove_connection(&self)

Remove a connection from the pool.

This might not happen immediately.

Do not call this function when there are no more connections managed by the pool. The requests to reduce the number of connections will are taken from a queue.

pub fn stats(&self) -> PoolStats

Get some statistics from the pool.

This locks the underlying pool.

Trait Implementations

impl RedisPool for SingleNodePool

fn check_out(&self) -> Checkout

Checkout a new connection and if the request has to be enqueued use a timeout as defined by the implementor.

fn check_out_explicit_timeout(&self, timeout: Option<Duration>) -> Checkout

Checkout a new connection and if the request has to be enqueued use the given timeout or wait indefinetly.

impl Clone for SingleNodePool

fn clone(&self) -> SingleNodePool

Returns a copy of the value.

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

Performs copy-assignment from source.
