@ingroup UCP_COMM @brief UCP operation fields and flags

The enumeration allows specifying which fields in @ref ucp_request_param_t are present and operation flags are used. It is used to enable backward compatibility support.

Variants

UCP_OP_ATTR_FIELD_REQUEST = 1

< request field

UCP_OP_ATTR_FIELD_CALLBACK = 2

< cb field

UCP_OP_ATTR_FIELD_USER_DATA = 4

< user_data field

UCP_OP_ATTR_FIELD_DATATYPE = 8

< datatype field

UCP_OP_ATTR_FIELD_FLAGS = 16

< operation-specific flags

UCP_OP_ATTR_FIELD_REPLY_BUFFER = 32

< reply_buffer field

UCP_OP_ATTR_FIELD_MEMORY_TYPE = 64

< memory type field

UCP_OP_ATTR_FIELD_RECV_INFO = 128

< recv_info field

UCP_OP_ATTR_FLAG_NO_IMM_CMPL = 65_536

< deny immediate completion

UCP_OP_ATTR_FLAG_FAST_CMPL = 131_072

< expedite local completion, even if it delays remote data delivery. Note for implementer: this option can disable zero copy and/or rendezvous protocols which require synchronization with the remote peer before releasing the local send buffer

UCP_OP_ATTR_FLAG_FORCE_IMM_CMPL = 262_144

< force immediate complete operation, fail if the operation cannot be completed immediately

UCP_OP_ATTR_FLAG_MULTI_SEND = 524_288

< optimize for bandwidth of multiple in-flight operations, rather than for the latency of a single operation

Trait Implementations

impl Clone for ucp_op_attr_t

fn clone(&self) -> ucp_op_attr_t

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ucp_op_attr_t

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

Formats the value using the given formatter.

impl Hash for ucp_op_attr_t

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ucp_op_attr_t

fn eq(&self, other: &ucp_op_attr_t) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
