Macro query_args 

query_args!() { /* proc-macro */ }

The macro returns a tuple containing the query and the parameter slice that can be used to call the various query methods provided by rust_postgres/tokio_postgres.

Please refer to the crate level documentation for an overview of the syntax.

A complete example could look something like:

let name = "Fred";
let surname = "Flintstone";
let (query, params) = query_args!(
    r"INSERT INTO flintstone($[name, surname]) VALUES($[..])",
    Args { name, surname }
);

txn.execute(query, params).await?;
