Struct CanAddr

pub struct CanAddr(/* private fields */);

CAN socket address.

This is the address for use with CAN sockets. It is simply an addres to the SocketCAN host interface. It can be created by looking up the name of the interface, like “can0”, “vcan0”, etc, or an interface index can be specified directly, if known. An index of zero can be used to read frames from all interfaces.

This is based on, and compatible with, the sockaddr_can struct from libc. ref

Implementations

impl CanAddr

pub fn new(ifindex: u32) -> Self

Creates a new CAN socket address for the specified interface by index. An index of zero can be used to read from all interfaces.

pub fn from_iface(ifname: &str) -> Result<Self>

Try to create an address from an interface name.

pub fn as_ptr(&self) -> *const sockaddr_can

Gets the address of the structure as a sockaddr_can pointer.

pub fn as_sockaddr_ptr(&self) -> *const sockaddr

Gets the address of the structure as a sockaddr pointer.

pub fn len() -> usize

Gets the size of the address structure.

pub fn into_storage(self) -> (sockaddr_storage, socklen_t)

Converts the CAN address into a sockaddr_storage type. This is a generic socket address container with enough space to hold any address type in the system.

Trait Implementations

impl AsRef<sockaddr_can> for CanAddr

fn as_ref(&self) -> &sockaddr_can

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CanAddr

fn clone(&self) -> CanAddr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CanAddr

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

Formats the value using the given formatter.

impl Default for CanAddr

fn default() -> Self

Returns the “default value” for a type.

impl From<sockaddr_can> for CanAddr

fn from(addr: sockaddr_can) -> Self

Converts to this type from the input type.

impl Copy for CanAddr
