Struct QueuePair 

pub struct QueuePair { /* private fields */ }

An RDMA Queue Pair (ibv_qp).

Implementations

impl QueuePair

pub fn qp_num(&self) -> u32

QP number assigned by the HCA.

pub fn state(&self) -> QpState

Current QP state.

pub fn modify(&self, attr: &mut ibv_qp_attr, attr_mask: u32) -> Result<()>

Modify the QP with the given attribute mask.

This is the low-level modify call. For convenience, use to_init, to_rtr, to_rts.

pub fn to_init( &self, port_num: u8, pkey_index: u16, access_flags: u32, ) -> Result<()>

Transition QP to INIT state.

pub fn to_rtr( &self, dest_qp_num: u32, rq_psn: u32, dgid: &ibv_gid, port_num: u8, ) -> Result<()>

Transition QP to RTR state (for RC QPs).

dest_qp_num: remote QP number. rq_psn: starting PSN for receive. dgid: destination GID. port_num: local port.

pub fn to_rts(&self, sq_psn: u32) -> Result<()>

Transition QP to RTS state.

pub fn post_send(&self, wr: &mut SendWr) -> Result<()>

Post a send work request (legacy API).

pub fn post_recv(&self, wr: &mut RecvWr) -> Result<()>

Post a receive work request (legacy API).

pub fn query(&self, attr_mask: u32) -> Result<(ibv_qp_attr, ibv_qp_init_attr)>

Query the QP.

pub fn as_raw(&self) -> *mut ibv_qp

Raw pointer (for advanced/FFI use).
