I can’t add rust agent to my wasn?

[aliscie]

When I add

[dependencies]
ic-agent = "0.20.0"

To Cargo.toml I got this error

Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.

I tride older versions but nothing

Correct. The agent is for client-side code (and for browsers, js-sys support has not been added yet). For canisters you would use ic_cdk::call, and for browsers you would use agent-js.

I tried using it but what is the ArgumentEncoder??

async move {
        let greeting = call(principal, "greet", ("Ali")).await.unwrap();
    };

error

    |                        ----                     ^^^^^^^ the trait `ArgumentEncoder` is not implemented for `&str`

[adamspofford-dfinity]

Add a comma: ("Ali",)

Otherwise ("Ali") is the same thing as writing "Ali".

Wanted to clarify, does this mean that agent-rs won't work for a Rust application that's compiled to WASM and runs in the browser?

[adamspofford-dfinity]

Correct. This is a feature in our backlog, but for now, if you wanted to interact with the IC from browser wasm, your best bet is agent-js through wasm_bindgen.

Closing as the stated issue is intended behavior.
