Struct Server 

pub struct Server {
    pub addr: ServerAddr,
    pub failed_attempts: usize,
    pub did_connect: bool,
    pub is_discovered: bool,
    pub last_error: Option<String>,
}

Metadata about a server in the connection pool.

This is a snapshot of the server’s state at the time it was queried. Modifying this struct has no effect on the connection.

Examples

let client = async_nats::connect("demo.nats.io").await?;
let pool = client.server_pool().await?;
for server in &pool {
    println!(
        "{:?}: {} failed attempts, connected: {}",
        server.addr, server.failed_attempts, server.did_connect
    );
}

Fields

addr: ServerAddr

The server address.

failed_attempts: usize

Number of consecutive failed connection attempts to this server. Reset to zero on a successful connection.

did_connect: bool

Whether the client has ever successfully connected to this server.

is_discovered: bool

Whether this server was discovered from a cluster INFO message rather than explicitly configured by the user.

last_error: Option<String>

The last connection error for this server, if any.
