Struct Mapped 

pub struct Mapped {
    pub type_param: String,
    pub constraint: Box<TsValue>,
    pub value_type: Box<TsValue>,
    pub key_modifier: MappedKeyModifier,
    pub constraint_type: MappedConstraint,
}

映射类型，表示 { [K in keyof T]: V } 或类似形式

Fields

type_param: String

类型参数名称 (K)

constraint: Box<TsValue>

键的来源类型 (keyof T)

value_type: Box<TsValue>

值类型表达式，可以引用类型参数

key_modifier: MappedKeyModifier

键修饰符

constraint_type: MappedConstraint

约束类型

Implementations

impl Mapped

pub fn new(type_param: String, constraint: TsValue, value_type: TsValue) -> Self

创建新的映射类型

pub fn with_optional(self) -> Self

设置为可选属性

pub fn with_readonly(self) -> Self

设置为只读属性

pub fn with_constraint(self, constraint: MappedConstraint) -> Self

设置约束类型

Trait Implementations

impl Clone for Mapped

fn clone(&self) -> Mapped

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapped

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

Formats the value using the given formatter.

impl Hash for Mapped

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 Mapped

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