Confidence Rust Flags Resolver

The Confidence Flag Resolver implemented in Rust, plus example hosts and a Cloudflare Worker build. This workspace compiles the core resolver to native and WebAssembly and demonstrates how to call it from Go, Node.js, Python, and Java.

Repository layout

• confidence-resolver: Core resolver crate
• confidence-cloudflare-resolver: Cloudflare Worker-compatible WASM target
• wasm-msg: Minimal WASM messaging layer shared by hosts
• wasm/*-host: Small host apps (Go, Node.js, Python, Java) calling the resolver. These are only intended to be examples, as well as being used for integration tests.
• data/: Sample local development data (e.g., resolver state)

Prerequisites

• Rust (stable) and the wasm32-unknown-unknown target
• For examples: Go, Node.js + Yarn, Python 3, Java + Maven
• Optional: Cloudflare Wrangler if you plan to deploy the Worker

Install the WASM target:

rustup target add wasm32-unknown-unknown

Common tasks

• Build all targets:

make build

• Test core resolver:

make test

• Lint all crates:

make lint

Running the example hosts

There are host implementations for different languages in the wasm folder. They are used for integration tests, but if you want you manually run them:

make run-go-host
make run-js-host
make run-python-host
make run-java-host

Cloudflare Worker build

Build the Cloudflare-compatible resolver (WASM):

make cloudflare

You can then integrate with Wrangler using confidence-cloudflare-resolver/wrangler.toml.
