Struct tuber::Func

pub struct Func { /* private fields */ }

定義済み関数を表現する

関数とラムダ抽象はよく似ているが、関数が 0 以上の arity を持つ点で異なる

Implementations

impl Func

pub fn name(&self) -> &str

pub fn params(&self) -> &Vec<Identifier>

pub fn body(&self) -> &Expr

pub fn arity(&self) -> usize

関数の引数の個数

0 以上の整数値を返す

pub fn apply(&self, args: Vec<Expr>) -> Expr

関数に引数を与え評価した結果を返す

Trait Implementations

impl Clone for Func

fn clone(&self) -> Func

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Func

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

Formats the value using the given formatter.

impl Display for Func

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

Formats the value using the given formatter.

impl Format for &Func

fn format(&self, style: &DisplayStyle) -> String

impl Format for Func

fn format(&self, style: &DisplayStyle) -> String

impl From<Func> for Expr

fn from(f: Func) -> Expr

Converts to this type from the input type.

impl PartialEq<Func> for Func

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

This method tests for self and other values to be equal, and is used by ==.

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

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