@ingroup UCP_CONTEXT @brief Context attributes.

The structure defines the attributes that characterize the particular context.

Aliased Type

struct ucp_context_attr_t {
    pub field_mask: u64,
    pub request_size: u32,
    pub thread_mode: ucs_thread_mode_t,

}

Fields

field_mask: u64

Mask of valid fields in this structure, using bits from @ref ucp_context_attr_field. Fields not specified in this mask will be ignored. Provides ABI compatibility with respect to adding new fields.

request_size: u32

Size of UCP non-blocking request. When pre-allocated request is used (e.g. in @ref ucp_tag_recv_nbr) it should have enough space to fit UCP request data, which is defined by this value.

thread_mode: ucs_thread_mode_t

Thread safe level of the context. For supported thread levels please see @ref ucs_thread_mode_t.

memory_types: u64

Mask of which memory types are supported, for supported memory types please see @ref ucs_memory_type_t.

name: [i8; 32]

Tracing and analysis tools can use name to identify this UCX context.
