Struct RenderedSignature 

pub struct RenderedSignature {
    pub name: Rc<str>,
    pub arity: Option<u16>,
    pub trait_name: Option<Rc<str>>,
}

A FunctionSignature that can be rendered into text. One can be obtained by calling FunctionSignature::render.

Fields

name: Rc<str>

arity: Option<u16>

This arity number does not include the implicit self argument.

trait_name: Option<Rc<str>>

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

Implementations

impl RenderedSignature

pub const INVALID_NAME: &'static str = ""

The empty string name is considered to be the invalid name, and will result in different Display.

pub fn invalid() -> Self

pub fn is_invalid(&self) -> bool

Trait Implementations

impl Clone for RenderedSignature

fn clone(&self) -> RenderedSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderedSignature

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

Formats the value using the given formatter.

impl Display for RenderedSignature

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

Formats the value using the given formatter.

impl Hash for RenderedSignature

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 RenderedSignature

fn eq(&self, other: &RenderedSignature) -> 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.
