v0.1.0 (2024-09-01)

Documentation

• provide description and license for release
• add FujiZ as one of the authors

New Features

• provide query_gid_table for convenient GID operations To keep compatibility, we would scan sysfs to get gid table when there is no ibv_query_gid_table symbol in libibverbs, just as what they do in the libibverbs original C implementation.
• implement trait for CQ A trait called CompletionQueue is introduced to interact with other modules in this crate; The original wrapper struct for ibv_cq and ibv_cq_ex are renamed to BasicCompletionQueue and ExtendedCompletionQueue, respectively.
• add setup method for each fields in grh
• add more attr for INIT -> RTR transition Note that the example will fail with current setup.
• implement modify on QueuePair Construct QueuePairAttribute using builder pattern and modify the QP through QueuePair::modify().
• add support for qp and qp_ex
• add create_comp_channel and create_cq_builder
• add support for cq and comp_channel
  1. implement generic builder for both cq and cq_ex
  2. implement comp_channel and associate its lifetime with cq
• an initial implementation of safe wrapper on rdmacm
• an initial implementation of safe wrapper on ibverbs

Bug Fixes

• fix modifying QP to RTR and add modify to RTS

Other

• change rdma-mummy-sys to depend on release version Create a placeholder for changelog at the same time.

Refactor

• use enum Mtu instead of u32 as parameter
• move comp_channel and cq to completion module
