Enum Pattern 

pub enum Pattern {
    Identifier(String),
    Object(Vec<ObjPatProp>),
    Array(Vec<ArrPatElem>),
    Expr(Box<Expression>),
}

束縛パターン（分割代入・引数）。

Variants

Identifier(String)

Object(Vec<ObjPatProp>)

{ a, b: c, d = 1, ...rest }

Array(Vec<ArrPatElem>)

[ a, , b = 1, ...rest ]

Expr(Box<Expression>)

メンバー/添字式への代入ターゲット（for (obj.prop of arr) / for (obj[k] of arr) 用）。 分割代入の宣言では使わず、非宣言形式 for-of/for-in の代入先としてのみ生成される。

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.

impl PartialEq for Pattern

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