Using a rust crate from crates.io

[RayyanAnsari]

Hi,
I've read the docs for integrating rust code within a flutter app, however, they all create their own rust crate and write code into lib.rs and api.rs. All I want to do is use the functions from an existing rust crate published on crates.io - how do I do this?

I guess maybe https://cjycode.com/flutter_rust_bridge/feature/lang_external.html#types-in-other-crates?

And feel free to PR to improve the automation that makes you write even less code for mirroring a crate!

I tried to use flutter_rust_bridge_codegen on the library's lib.rs and I got this output:

Error: Failed to parse function output type `HashMap<PluginID,PluginInfo>`

Map is not supported yet, but should be easy to PR by the following approach: Just mimic how a String is implemented (delegate its implementation to Vec<u8>), we can handle HashMap<K,V> by delegating to Vec<(K,V)>
