Version 0.24.0 of the agent-rs family of crates is now available on crates.io. The headline of the release is that the Rust agent can now be used from the browser via wasm-bindgen. This means that, if you wanted to, you can now write both backend and frontend without leaving the Rust ecosystem, using wasm-pack and a Rust frontend system like yew.
To add the agent to a Rust frontend project, add the following to Cargo.toml, under [dependencies]:
ic-agent = { version = "0.24", features = ["wasm-bindgen"] }
ic-utils will work in the frontend as long as the feature is enabled in ic-agent. Note that at this time NodeJS is not supported.
