Implementations

impl Value

pub fn is_object(&self) -> bool

Returns true if the value is an object.

pub fn as_object(&self) -> Option<&BTreeMap<ObjectKey, Value>>

If the value is an object, returns the associated BTreeMap. Returns None otherwise.

pub fn as_object_mut(&mut self) -> Option<&mut BTreeMap<ObjectKey, Value>>

If the value is an object, returns the associated mutable BTreeMap. Returns None otherwise.

pub fn is_array(&self) -> bool

Returns true if the value is an array.

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

If the value is an array, returns the associated Vec. Returns None otherwise.

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

If the value is an array, returns the associated mutable Vec. Returns None otherwise.

pub fn is_bytes(&self) -> bool

Returns true if the value is a byte string.

pub fn as_bytes(&self) -> Option<&Vec<u8>>

Returns the associated byte string or None if the value has a different type.

pub fn as_bytes_mut(&mut self) -> Option<&mut Vec<u8>>

Returns the associated mutable byte string or None if the value has a different type.

pub fn is_string(&self) -> bool

Returns true if the value is a string.

pub fn as_string(&self) -> Option<&String>

Returns the associated string or None if the value has a different type.

pub fn as_string_mut(&mut self) -> Option<&mut String>

Returns the associated mutable string or None if the value has a different type.

pub fn is_number(&self) -> bool

Retrns true if the value is a number.

pub fn is_i64(&self) -> bool

Returns true if the Value is a i64. Returns false otherwise.

pub fn is_u64(&self) -> bool

Returns true if the Value is a u64. Returns false otherwise.

pub fn is_f64(&self) -> bool

Returns true if the Value is a f64. Returns false otherwise.

pub fn as_i64(&self) -> Option<i64>

If the Value is a number, return or cast it to a i64. Returns None otherwise.

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

If the Value is a number, return or cast it to a u64. Returns None otherwise.

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

If the Value is a number, return or cast it to a f64. Returns None otherwise.

pub fn is_boolean(&self) -> bool

Returns true if the value is a boolean.

pub fn as_boolean(&self) -> Option<bool>

If the value is a Boolean, returns the associated bool. Returns None otherwise.

pub fn is_null(&self) -> bool

Returns true if the value is a Null. Returns false otherwise.

pub fn as_null(&self) -> Option<()>

If the value is a Null, returns (). Returns None otherwise.

Trait Implementations

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Value

fn deserialize<D>( deserializer: D, ) -> Result<Value, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

fn from(v: BTreeMap<ObjectKey, Value>) -> Value

Converts to this type from the input type.

impl From<ObjectKey> for Value

fn from(key: ObjectKey) -> Value

Converts to this type from the input type.

impl From<String> for Value

fn from(v: String) -> Value

Converts to this type from the input type.

impl From<Vec<Value>> for Value

fn from(v: Vec<Value>) -> Value

Converts to this type from the input type.

impl From<Vec<u8>> for Value

fn from(v: Vec<u8>) -> Value

Converts to this type from the input type.

impl From<bool> for Value

impl PartialEq for Value

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

where S: Serializer,

Serialize this value into the given Serde serializer.
