pub struct Dfn {
    pub lts: Vec<Lt>,
    pub tys: Vec<Type>,
    pub ret: Type,
}

Stores preloaded function constraints. These are already checked.

Fields

lts: Vec<Lt>

Lifetimes of argument.

tys: Vec<Type>

Argument types of function.

ret: Type

Return type of function.

Methods

impl Dfn

pub fn nl(args: Vec<Type>, ret: Type) -> Dfn

Creates a new function signature with no lifetime.

pub fn new(f: &Function) -> Dfn

Creates new function signature from an AST function.

pub fn returns(&self) -> bool

Returns true if the function returns something.
