Implementations

impl Value

pub fn is_null(&self) -> bool

Tests whether this value is a null.

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

Extracts the integer value if it is an integer.

pub fn is_integer(&self) -> bool

Tests whether this value is an integer.

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

Extracts the float value if it is a float.

pub fn is_float(&self) -> bool

Tests whether this value is a float.

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

Extracts the boolean value if it is a boolean.

pub fn is_bool(&self) -> bool

Tests whether this value is a boolean.

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

Extracts the string of this value if it is a string.

pub fn is_str(&self) -> bool

Tests if this value is a string.

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

Extracts the array value if it is an array.

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

Extracts the array value if it is an array.

pub fn is_array(&self) -> bool

Tests whether this value is an array.

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

Extracts the list values if it is a tuple.

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

Extracts the list values if it is a tuple.

pub fn is_tuple(&self) -> bool

Tests whether this value is a tuple.

pub fn as_assoc(&self) -> Option<&HashMap<String, Value>>

Extracts the objects value if it is an assoc.

pub fn as_assoc_mut(&mut self) -> Option<&mut HashMap<String, Value>>

Extracts the objects value if it is an assoc.

pub fn is_assoc(&self) -> bool

Tests whether this value is an assoc.

pub fn as_variant(&self) -> Option<&Variant>

Extracts the variant value if it is a variant.

pub fn as_variant_mut(&mut self) -> Option<&mut Variant>

Extracts the variant value if it is a variant.

pub fn is_variant(&self) -> bool

Tests whether this value is a variant.

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

Tests whether this and another value have the same type.

pub fn type_str(&self) -> &'static str

Returns a human-readable representation of the type of this value.

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<'de> Deserialize<'de> for Value

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Value

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

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
