Enum JsonValue 

pub enum JsonValue {
    Null,
    Bool(bool),
    Number(String),
    String(String),
    Array(Vec<Value>),
    Object(Vec<(String, Value)>),
}

Lossless JSON value used by the document model. Dependency-free JSON value that preserves number lexemes and object order.

Variants

Null

JSON null.

Bool(bool)

JSON boolean.

Number(String)

JSON number stored as its original lexical representation.

String(String)

JSON string.

Array(Vec<Value>)

JSON array.

Object(Vec<(String, Value)>)

JSON object represented as ordered key/value pairs.

Implementations

impl Value

pub fn parse(input: &[u8]) -> Result<Self, String>

Parses one complete JSON value.

pub fn to_vec(&self) -> Vec<u8>

Serializes this value as whitespace-free JSON.

pub fn as_object(&self) -> Option<&[(String, Value)]>

Borrows object entries when this value is an object.

pub fn is_object(&self) -> bool

Returns whether this value is an object.

pub fn as_object_mut(&mut self) -> Option<&mut Vec<(String, Value)>>

Mutably borrows object entries when this value is an object.

pub fn as_array(&self) -> Option<&[Value]>

Borrows array entries when this value is an array.

pub fn as_array_mut(&mut self) -> Option<&mut Vec<Value>>

Mutably borrows array entries when this value is an array.

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

Borrows the string when this value is a string.

pub fn as_u64(&self) -> Option<u64>

Parses a non-negative integer without changing its stored lexeme.

pub fn as_f64(&self) -> Option<f64>

Parses a JSON number as f64 without changing its stored lexeme.

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

Looks up an object member by key.

pub fn get_mut(&mut self, key: &str) -> Option<&mut Value>

Mutably looks up an object member by key.
