Struct j2534::Interface

pub struct Interface { /* fields omitted */ }

Represents a J2534 library

Methods

impl Interface

pub fn new<S: AsRef<OsStr>>(path: S) -> Result<Interface>

Returns a J2534 library given the path

Arguments

• path - The absolute path to the J2534 shared library

Example

use j2534::Interface;
let interface = Interface::new("C:\\j2534_driver.dll").unwrap();

pub fn get_last_error(&self) -> Result<String>

Returns a text description of the most recent error

pub fn open<S: Into<Vec<u8>>>(&self, port: S) -> Result<Device>

Creates a Device from the PassThru interface connected to the given port

Arguments

• port - The port to search for a J2534 device

Example

use j2534::Interface;
let interface = Interface::new("C:\\j2534_driver.dll").unwrap();
let device = interface.open("COM2").unwrap();

pub fn open_any(&self) -> Result<Device>

Creates a Device from any connected PassThru devices

Example

use j2534::Interface;
let interface = Interface::new("C:\\j2534_driver.dll").unwrap();
let device = interface.open_any().unwrap();

pub unsafe fn ioctl(
    &self,
    handle: u32,
    id: IoctlId,
    input: *mut c_void,
    output: *mut c_void
) -> Result<i32>

General purpose I/O control for modifying device or channel characteristics.
