Struct Signature 

pub struct Signature {
    pub ret: Ty,
    pub params: Vec<Ty>,
    pub variadic: bool,
    pub prototyped: bool,
}

A function’s signature.

Fields

ret: Ty

The return type.

params: Vec<Ty>

The parameter types.

variadic: bool

Whether the prototype ended with , ....

prototyped: bool

Whether a parameter type list was given at all; see FuncType::prototyped.

int f(); before C23 declares a function whose parameters are unspecified: params is empty because nothing was said, not because there are none. A definition written that way does take no parameters — that is what the generated item has — but its type still has no prototype, so a call with arguments is legal C and reaches the callee with the default argument promotions applied.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Signature

impl PartialEq for Signature

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
