Struct PortInfo 

pub struct PortInfo {
    pub port: u16,
    pub protocol: Protocol,
    pub pid: u32,
    pub process_name: String,
    pub address: Option<String>,
}

Information about a listening port

Fields

port: u16

Port number

protocol: Protocol

Protocol (TCP/UDP)

pid: u32

Process ID using this port

process_name: String

Process name

address: Option<String>

Bind address (e.g., “0.0.0.0”, “127.0.0.1”, “::”)

Implementations

impl PortInfo

pub fn get_all_listening() -> Result<Vec<PortInfo>>

Get all listening ports on the system, port ascending and, for one port, PID ascending. The system lists them in its own order (lsof’s on macOS, the kernel’s socket table on Linux, netstat’s on Windows), so the order is fixed here once for everything that reads ports: a process’s ports are ascending in on, for and why, and the holders of a port are by PID.

pub fn holders_of(port: u16) -> Result<Vec<PortInfo>>

Every process listening on a port, each once, PID ascending (empty when nothing listens). One port number can be held by several processes: 127.0.0.1 and [::1] are different sockets.

pub fn get_process(&self) -> Result<Option<Process>>

Get the full process info for this port’s process

pub fn is_exposed(&self) -> bool

Whether the port is open to the network: bound to every address. A port with no known address counts as open.

pub fn is_local(&self) -> bool

Whether the port is bound to loopback only
