海外TECH	DEV Community	Apache APISIX loves Rust! (and me too)	https://dev.to/apisix/apache-apisix-loves-rust-and-me-too-1n73	Apache APISIX loves Rust and me too Apache APISIX is built upon the shoulders of two giants NGINX a widespread Open Source reverse proxyOpenResty a platform that allows scripting NGINX with the Lua programming language via LuaJITThis approach allows APISIX to provide out of the box Lua plugins that should fit most business requirements But it always comes a time when generic plugins don t fit your requirements In this case you can write your own Lua plugin However if Lua is not part of your tech stack diving into a new ecosystem is a considerable investment Therefore Apache APISIX offers developers to write plugins in several other languages In this post I d like to highlight how to write such a plugin with Rust A bit of contextBefore I dive into the how let me first describe a bit of context surrounding the Rust integration in Apache APISIX I believe it s a good story because it highlights the power of Open Source It starts with the Envoy proxy Envoy is an open source edge and service proxy designed for cloud native applications Around Envoy s developers realized a simple truth Since Envoy is a statically compiled binary integrators who need to extend it must compile it from the modified source instead of using the official binary version Issues range from supply chains more vulnerable to attacks to a longer drift when a new version is released For end users whose core business is much further it means having to hire specialized skills for this reason only The team considered to solve the issue with C extensions but discarded this approach as neither APIs nor ABIs were stable Instead they chose to provide a stable WebAssembly based ABI If you re interested in a more detailed background you can read the whole piece on GitHub The specification is available on GitHub Developers can create SDK for their tech stackProxy and API Gateway providers can integrate proxy wasm in their product Apache APISIX and proxy wasmThe Apache APISIX project decided to integrate proxy wasm into the product to benefit from the standardization effort It also allows end users to start with Envoy or any other proxy wasm compatible reverse proxy to migrate to Apache APISIX when necessary APISIX doesn t implement proxy wasm but integrates wasm nginx module It s an Apache v licensed project provided by api ai one of the main contributors to Apache APISIX As its name implies integration is done at the NGINX level Let s code Now that we have explained how everything fits together it s time to code Preparing Rust for WebAssemblyBefore developing the first line of code we need to give Rust WASM compilation capabilities rustup target add wasm wasiIt allows the Rust compiler to output WASM code cargo build target wasm wasiThe WASM code is found in target wasm wasi debug sample wasmtarget wasm wasi release sample wasm when compiled with the release flag Setting up the projectThe setup of the project is pretty straightforward cargo new sample lib Create a lib project with the expected structure The code itselfLet me first say that the available documentation is pretty sparse For example proxy wasm s is limited to the methods signature think JavaDocs Rust SDK is sample based However one can get some information from the C SDK WASM module is running in a stack based virtual machine and its memory is isolated from the host environment All interactions between host and WASM module are through functions and callbacks wrapped by context object At bootstrap time a root context is created The root context has the same lifetime as the VM runtime instance and acts as a target for any interactions which happen at initial setup It is also used for interactions that outlive a request At request time a context with incremental is created for each stream Stream context has the same lifetime as the stream itself and acts as a target for interactions that are local to that stream The Rust code maps to the same abstractions Here s the code for a very simple plugin that logs to prove that it s invoked use log warn use proxy wasm traits Context HttpContext use proxy wasm types Action LogLevel proxy wasm main proxy wasm set log level LogLevel Trace proxy wasm set http context gt Box lt dyn HttpContext gt Box new HttpCall struct HttpCall impl Context for HttpCall impl HttpContext for HttpCall fn on http request headers amp mut self usize bool gt Action warn on http request headers Action Continue Set the log level to Apache APISIX s defaultSet the HTTP context to create for each requestNeed to implement Context By default all functions are implemented in Context so implementation is not mandatoryLikewise for HttpContextImplement the function Functions in HttpContext refer to a phase in the ABI lifecycle when headers are decoded It should return an Action whose value is either Continue or Pause Log finallyAfter generating the WebAssembly code see above we have to configure Apache APISIX Configuring Apache APISIX for WASMApache APISIX s documentation is geared toward Go Still since both Go and Rust generate WebAssembly we can reuse most of it We need to declare each WASM plugin wasm plugins name sample priority file opt apisix wasm sample wasmThen we can use the plugin like any other routes uri upstream type roundrobin nodes httpbin org plugins sample conf dummy ENDPlugin nameAt the moment the conf attribute is mandatory and must be non empty on the Apache APISIX validation side even though we don t configure anything on the Rust sideAt this point we can ping the endpoint curl localhost The result is as expected rust wasm plugin apisix warn on http request headers client server request GET HTTP host localhost ConclusionIn this post I described the history behind the proxy wasm and how Apache APISIX integrates it via the WASM Nginx module I explained how to set up your Rust local environment to generate WebAssembly Finally I created a dummy plugin and deployed it to Apache APISIX In the next post we ll beef up the plugin to provide valuable capabilities The source code is available on GitHub
