Enum Value 

pub enum Value {
    Null,
    Bool(bool),
    Int(i64),
    Float(f64),
    Str(String),
    Array(Vec<Value>),

}

Variants

Null

Bool(bool)

Int(i64)

Float(f64)

Str(String)

Array(Vec<Value>)

Object(BTreeMap<String, Value>)

对象/块; __type / __name 裸块元数据以保留字键存放

Implementations

impl Value

pub fn get(&self, path: &str) -> Option<&Value>

对象字段按需取 (支持 “.” 点路径)

pub fn as_str(&self) -> Option<&str>

字符串视图 (字符串直接返回; 其它返回 None)

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

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

Equality operator ==.

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

Inequality operator !=.

impl SmlDeserialize for Value

fn from_sml_value(v: &Value) -> Result<Self, String>

fn from_sml(text: &str) -> Result<Self, String>

impl SmlSerialize for Value

fn to_sml_value(&self) -> Value

fn to_sml(&self) -> String
