Struct MctpLinuxEp

pub struct MctpLinuxEp { /* private fields */ }

Encapsulation of a remote endpoint: a socket and an Endpoint ID.

Implementations

impl MctpLinuxEp

pub fn new(eid: u8, net: u32) -> Result<Self>

Create a new MCTPEndpoint with EID eid

fn main() -> std::io::Result<()> {
    const EID : u8 = 8;

    // Create a new endpoint using the linux socket support
    let mut ep = MctpLinuxEp::new(EID, MCTP_NET_ANY)?;

    // for subsequent use of `ep`, we're just interacting with the
    // mctp::Endpoint trait, which are independent of the socket support

    // Get Endpoint ID message: command 0x02, no data. Allow the MCTP stack
    // to allocate an owned tag.
    let tx_buf = vec![0x02u8];
    ep.send(MCTP_TYPE_CONTROL, Tag::OwnedAuto, &tx_buf)?;

    // Receive a response. We create a 16-byte vec to read into; ep.recv()
    // will return the sub-slice containing just the response data.
    let mut rx_buf = vec![0u8; 16];
    let (rx_buf, eid, tag) = ep.recv(&mut rx_buf)?;

    println!("response from {}, tag {}: {:x?}", eid, tag, rx_buf);

    Ok(())
}

pub fn try_clone(&self) -> Result<Self>

Clone this endpoint.

Creates a separate socket descriptor for the new endpoint.

pub fn as_socket(&mut self) -> &mut MctpSocket

Borrow the internal MCTP socket

Trait Implementations

impl Endpoint for MctpLinuxEp

fn bind(&mut self, typ: MsgType) -> Result<()>

Bind the endpoint’s socket to a type value, so we can receive incoming requests from this endpoint.

Note that this only specifies the local EID for the bind; there can only be one bind of that type for any one network.

fn send_vectored( &mut self, typ: MsgType, tag: Tag, bufs: &[&[u8]], ) -> Result<()>

Send a message to this endpoint, blocking.

fn recv<'f>(&mut self, buf: &'f mut [u8]) -> Result<(&'f mut [u8], Eid, Tag)>

Blocking recieve from this endpoint.

fn send(&mut self, typ: MsgType, tag: Tag, buf: &[u8]) -> Result<(), Error>

Send a message to this endpoint, blocking.
