Rust bindings and RPC components for vAccel

Crates implementing Rust interfaces for the vAccel C library:

• The vaccel-bindings crate provides Rust bindings for vAccel
• The vaccel-rpc-proto, vaccel-rpc-agent and vaccel-rpc-client crates implement RPC-based transport for vAccel operations. They can be used directly, to interact with vAccel from Rust, or through the C interface, to implement transport plugins for vAccel.

Install vAccel

Install vAccel with:

wget https://s3.nbfc.io/nbfc-assets/github/vaccel/rev/main/x86_64/release/vaccel_latest_amd64.deb
sudo dpkg -i vaccel_latest_amd64.deb

Build the components

First clone the repo:

git clone git@github.com:nubificus/vaccel-rust
cd vaccel-rust

Build with Cargo

All Rust components can be used as dependencies and be built with Cargo as usual. This repo is structured as a Cargo workspace so all crates can be compiled from the root directory.

cargo build

will build the vaccel-rpc-agent (and dependencies)

Crates can also be built separately, ie.:

cargo build -p vaccel-bindings

will build vaccel-bindings (and dependencies).

Build with Meson

A Meson build is also provided for ease of integration with vAccel. The Meson implementation uses Cargo for the actual build and provides build targets for vaccel-rpc-agent and vaccel-rpc-client. To build with Meson:

meson setup build
meson compile -C build

This will build vaccel-rpc-agent (and dependencies) using sync ttrpc.

To also build vaccel-rpc-client use:

meson setup -Drpc-client=enabled build
meson compile -C build

There is experimental support for a Rust RPC agent/client based on async ttrpc and a streaming implementation of the vAccel genop operation. To compile with these features you can configure the project with:

# async ttrpc
meson setup -Dasync=enabled build

# async ttrpc with streaming genop
meson setup -Dasync-stream=enabled build
