Struct Call 

pub struct Call<'a> {
    pub row: &'a str,
    pub features: &'a [&'a str],
}

Which call a language is answering: the row it is through — the language’s name, or a set’s — and the features in force, the row’s own and whatever the caller laid over them, in declaration order.

Fields

row: &'a str

features: &'a [&'a str]
