Struct H2Pool 

pub struct H2Pool { /* private fields */ }

A pool of HTTP/2 connections. Cheap to clone (shares one Rc state).

Implementations

impl H2Pool

pub fn new<F, Fut>(factory: F, max_connections: usize) -> Self

where F: Fn() -> Fut + 'static, Fut: Future<Output = Result<Rc<dyn PoolConnection>, H2Error>> + 'static,

Build a pool from a connection factory (each call opens a fresh connection). max_connections caps how many connections are opened (usize::MAX for unbounded); past the cap, requests park on an existing connection (which queues them internally until a stream slot frees).

pub async fn request(&self, init: RequestInit) -> Result<Response, H2Error>

Route a request to a connection with a free stream slot, opening a new connection if all existing ones are saturated.

pub fn connections(&self) -> usize

The number of live connections currently in the pool.

pub fn close(&self)

Gracefully close every connection in the pool.

Trait Implementations

impl Clone for H2Pool

fn clone(&self) -> H2Pool

Returns a duplicate of the value.

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

Performs copy-assignment from source.
