Struct wpactrl::WpaCtrlAttached

pub struct WpaCtrlAttached(_, _);

A connection to wpasupplicant / hostap that receives status messages

Methods

impl WpaCtrlAttached

fn detach(self) -> Result<WpaCtrl>

Stop listening for and discard any remaining control interface messages

Examples

let mut wpa = wpactrl::WpaCtrl::new().open().unwrap().attach().unwrap();
wpa.detach().unwrap();

fn recv(&mut self) -> Result<Option<String>>

Receive the next control interface message.

Note that multiple control interface messages can be pending; call this function repeatedly until it returns None to get all of them.

Examples

let mut wpa = wpactrl::WpaCtrl::new().open().unwrap().attach().unwrap();
assert_eq!(wpa.recv().unwrap(), None);

fn request(&mut self, cmd: &str) -> Result<String>

Send a command to wpa_supplicant/hostapd.

Commands are generally identical to those used in wpa_cli, except all uppercase (eg LIST_NETWORKS, SCAN, etc)

Control interface messages will be buffered as the command runs, and will be returned on the next call to recv.

Examples

let mut wpa = wpactrl::WpaCtrl::new().open().unwrap();
assert_eq!(wpa.request("PING").unwrap(), "PONG\n");
