Struct Config 

pub struct Config {
    pub name: Option<String>,
    pub listener_ip: Option<IpAddr>,
    pub desired_listening_port: Option<u16>,
    pub allow_random_port: bool,
    pub fatal_io_errors: Vec<ErrorKind>,
    pub max_connections: u16,
    pub connection_timeout_ms: u16,
}

The Tcp’s configuration. See the source of Config::default for the defaults.

Fields

name: Option<String>

A user-friendly identifier of the Tcp. It is visible in the logs, where it allows Tcp instances to be distinguished more easily if multiple are run at the same time.

note: If set to None when the configuration is initially created, it will be automatically assigned (the string representation of) a sequential, zero-based numeric identifier. So this is essentially never None, in a running node.

listener_ip: Option<IpAddr>

The IP address the Tcp’s connection listener should bind to.

note: If set to None, the Tcp will not listen for inbound connections at all.

desired_listening_port: Option<u16>

The desired listening port of the Tcp. If Config::allow_random_port is set to true, the Tcp will attempt to bind its listener to a different port if the desired one is not available.

note: Config::listener_ip must not be None in order for it to have any effect.

allow_random_port: bool

Allow listening on a different port if Config::desired_listening_port is unavailable.

note: Config::listener_ip must not be None in order for it to have any effect.

fatal_io_errors: Vec<ErrorKind>

The list of IO errors considered fatal and causing the connection to be dropped.

note: Tcp needs to implement the Reading and/or Writing protocol in order for it to have any effect.

max_connections: u16

The maximum number of active connections Tcp can maintain at any given time.

note: This number can very briefly be breached by 1 in case of inbound connection attempts. It can never be breached by outbound connection attempts, though.

connection_timeout_ms: u16

The maximum time (in milliseconds) allowed to establish a raw (before the Handshake protocol) TCP connection.

Implementations

impl Config

pub fn new(listener_address: SocketAddr, max_connections: u16) -> Self

Initializes a new Tcp configuration with a listener address, a maximum number of connections, and the default values.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Initializes a new Tcp configuration with the default values.
