Struct ProtectionDomain 

pub struct ProtectionDomain { /* private fields */ }

An RDMA Protection Domain (ibv_pd).

All memory registrations and QPs belong to a PD.

Implementations

impl ProtectionDomain

pub fn new(ctx: Arc<Context>) -> Result<Arc<Self>>

Allocate a new PD on the given context.

pub unsafe fn from_raw(pd: *mut ibv_pd, ctx: Arc<Context>) -> Arc<Self>

Wrap a raw ibv_pd pointer.

Safety

The pointer must be valid and the caller must ensure ctx is the correct parent context.

pub fn reg_mr<'a>( self: &Arc<Self>, buf: &'a mut [u8], access: AccessFlags, ) -> Result<MemoryRegion<'a>>

Register a borrowed memory region.

The returned MemoryRegion borrows buf and keeps self alive via Arc.

pub fn reg_mr_owned( self: &Arc<Self>, buf: Vec<u8>, access: AccessFlags, ) -> Result<OwnedMemoryRegion>

Register an owned memory region.

The buffer is moved into the OwnedMemoryRegion and freed when it is dropped.

pub fn create_qp( self: &Arc<Self>, send_cq: &Arc<CompletionQueue>, recv_cq: &Arc<CompletionQueue>, init_attr: &QpInitAttr, ) -> Result<QueuePair>

Create a Queue Pair on this PD.

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

Raw pointer (for advanced/FFI use).

pub fn context(&self) -> &Arc<Context>

The parent context.
