Struct FunctionSignature 

pub struct FunctionSignature {
    pub name: Rc<str>,
    pub arity: Option<u16>,
    pub trait_id: Option<Opr24>,
}

The signature of a function (its name, argument count, and enclosing trait).

Fields

name: Rc<str>

arity: Option<u16>

This arity number does not include the implicit self argument.

trait_id: Option<Opr24>

The index of the trait this signature belongs to. When None, the function is free and does not belong to any trait.

Implementations

impl FunctionSignature

pub fn new(name: impl Into<Rc<str>>, arity: impl Into<Option<u16>>) -> Self

Creates a new function signature for a function that does not belong to a trait.

pub fn render(&self, env: &Environment) -> RenderedSignature

Renders this signature into one that can be formatted.

Trait Implementations

impl Clone for FunctionSignature

fn clone(&self) -> FunctionSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionSignature

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

Formats the value using the given formatter.

impl Hash for FunctionSignature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FunctionSignature

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
