Struct Signature 

pub struct Signature {
    pub name: &'static str,
    pub params: &'static [Param],
    pub variadic: bool,
    pub result: fn(&[Ty]) -> Result<Ty, Mismatch>,
}

Fields

name: &'static str

params: &'static [Param]

variadic: bool

join takes two to MAX_WIDTH components; nothing else takes an open tail.

result: fn(&[Ty]) -> Result<Ty, Mismatch>
