Milestones

Eval 1:

  •  Add the functionality to parse function signatures with associated types out of MIR to cbindgen (either by itself or in addition to Rust source code)
  •  Write tests that will cover the functionality of parsing associated types in cbindgen
  •  Open a PR to merge this code into cbindgen, progress with further tasks as we wait for this to be approved

Eval 2:

  •  Use iroha_ffi to generate extern functions out of existing Rust code
  •  Make corrections to the iroha_ffi library in this process if needed or write manual implementations of extern functions

Eval 3:

  •  Use cbindgen to generate C .h header files out of extern functions in the Rust source code
  •  Conduct manual testing
  •  Address the code bugs

Eval 43:

  •  Document the mentorship results
  •  Create a small app demonstrating that you have successfully linked the shared object with the C header files
  •  Present your results

Tasks/Plan

Status

June 1 - June 1424

revisit knowledge of Rust
run iroha nodes and connect to it via both `iroha_client_cli` and client app
run cbindgen on a small example: - export a function from Rust - generate C bindings with cbindgen - link this C lib from C and Java

done
June 15 25 - June 28Aug 23

fork the cbindgen repository
add the functionality to parse function signatures from MIR

June 29 - July 12

Aug Aug 10 - Aug 23Aug 24 - Sept 6Sept 7 - Sept 20

make use of ffi_export macro to generate FFI bindings of methods and functions in iroha_client
MIR approach failed - explore other approaches
