Struct Context 

pub struct Context { /* private fields */ }

An opened RDMA device context.

Wraps ibv_context*. Create via Device::open. All child resources (PD, CQ, QP, …) hold an Arc<Context> to keep the context alive.

Implementations

impl Context

pub fn create_cq(self: &Arc<Self>, cqe: i32) -> Result<Arc<CompletionQueue>>

Create a Completion Queue.

impl Context

pub unsafe fn from_raw(ctx: *mut ibv_context, owned: bool) -> Self

Wrap a raw ibv_context pointer.

Safety

The pointer must be valid. If owned is true, ibv_close_device will be called on drop. Set owned to false for rdma_cm-managed contexts.

pub fn query_device(&self) -> Result<ibv_device_attr>

Query device attributes.

pub fn query_port(&self, port_num: u8) -> Result<ibv_port_attr>

Query port attributes.

pub fn query_gid(&self, port_num: u8, index: i32) -> Result<ibv_gid>

Query a single GID entry by index.

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

Raw ibv_context pointer (for advanced/FFI use).

impl Context

pub fn alloc_pd(self: &Arc<Self>) -> Result<Arc<ProtectionDomain>>

Allocate a Protection Domain.
