This section is a work in progress.

Examples:

• ic_api

import {
    blob,
    bool,
    Canister,
    ic,
    int8,
    nat,
    query,
    text
} from 'azle/experimental';

export default Canister({
    // returns the length of the argument data in bytes
    argDataRawSize: query(
        [blob, int8, bool, text],
        nat,
        (arg1, arg2, arg3, arg4) => {
            return ic.argDataRawSize();
        }
    )
});
