mucking around with rust/c interop and unix datagrams

kv_ipc

Exploring a couple things in Rust:

• C program uses a Rust library
• Unix domain datagram sockets for interprocess communication

Components

• ./src/bin/example_client.c: a C program that calls the Rust library
• ./include/libkv_ipc_client.h: the C header for the Rust library
• ./src/lib.rs: Rust library
• ./src/bin/example_server.rs: a Rust program that receives messages from the C program

Building and testing

Build the components

cargo install cbindgen
cargo build
./regenerate_c_header.sh
./rebuild_example_client.sh

Launch the server, listening on a socket

./target/debug/example_server /tmp/my-socket

Send a message from the C program to that socket

./target/debug/example_client /tmp/my-socket
