Member Data Documentation

◆ fDistributionKey

daos_key_t ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fDistributionKey {}

The distribution key, as used by the daos_obj_{fetch,update} functions.

Definition at line 137 of file RDaos.hxx.

◆ fDkey

DistributionKey_t ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fDkey {}

A daos_key_t is a type alias of d_iov_t.

This type stores a pointer and a length. In order for fDistributionKey to point to memory that we own, fDkey holds the distribution key.

Definition at line 131 of file RDaos.hxx.

◆ fEvent

std::optional<daos_event_t> ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fEvent {}

Definition at line 140 of file RDaos.hxx.

◆ fIods

std::vector<daos_iod_t> ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fIods {}

Definition at line 138 of file RDaos.hxx.

◆ fRequests

std::span<RAkeyRequest> ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fRequests {}

fRequests is a sequential container assumed to remain valid throughout the fetch/update operation, holding a list of RAkeyRequest-typed elements.

Definition at line 134 of file RDaos.hxx.

◆ fSgls

std::vector<d_sg_list_t> ROOT::Experimental::Internal::RDaosObject::FetchUpdateArgs::fSgls {}
