Function arg_value_from_context

cel/src/magic.rs:258–262

Returns the next argument specified by the context's `arg_idx` field as after resolving it. Calling this multiple times will increment the `arg_idx` which will return subsequent arguments every time. Calling this function when there are no more arguments will result in a panic. Since this function is only ever called within the context of a controlled macro that calls it once for each argument, t

(ctx: &mut FunctionContext)

/// function is only ever called within the context of a controlled macro that calls it once
/// for each argument, this should never happen.
fn arg_value_from_context(ctx: &mut FunctionContext) -> Result<Value, ExecutionError> {
    let idx = ctx.arg_idx;
    ctx.arg_idx += 1;
    ctx.resolve(Argument(idx))
}
