Struct LapinConnectionManager 

Source
pub struct LapinConnectionManager { /* private fields */ }
Expand description

An r2d2::ManageConnection for lapin::Connections.

§Example

use lapin::ConnectionProperties;
use r2d2_lapin::prelude::*;
use std::thread;

let manager = LapinConnectionManager::new("amqp://guest:guest@127.0.0.1:5672//", &ConnectionProperties::default());
let pool = r2d2::Pool::builder()
    .max_size(15)
    .build(manager)
    .unwrap();

for _ in 0..20 {
    let pool = pool.clone();
    thread::spawn(move || {
        let conn = pool.get().unwrap();
        // use the connection
        // it will be returned to the pool when it falls out of scope.
    });
}
