The ValueTrait exposes common interface for values, this allows using both BorrowedValue and OwnedValue nearly interchangable

Required methods

fn get(&self, k: &str) -> Option<&Self>

Gets a ref to a value based on a key, returns None if the current Value isn't an Object or doesn't contain the key it was asked for.

fn get_mut(&mut self, k: &str) -> Option<&mut Self>

Same as get but returns a mutable ref instead

fn get_idx(&self, i: usize) -> Option<&Self>

Gets a ref to a value based on n index, returns None if the current Value isn't an Array or doesn't contain the index it was asked for.

fn get_idx_mut(&mut self, i: usize) -> Option<&mut Self>

Same as get_idx but returns a mutable ref instead

fn value_type(&self) -> ValueType

Returns the type of the current Valye

fn is_null(&self) -> bool

returns true if the current value is null

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

Tries to represent the value as a bool

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

Tries to represent the value as an i64

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

Tries to represent the value as a f64

fn cast_f64(&self) -> Option<f64>

Casts the current value to a f64 if possible, this will turn integer values into floats.

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

Deprecated since 0.1.20:

This will allocate a new string please use as_str instead

Tries to represent the value as a String

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

Tries to represent the value as a &str

fn as_array(&self) -> Option<&Self::Array>

Tries to represent the value as an array and returns a refference to it

fn as_array_mut(&mut self) -> Option<&mut Self::Array>

Tries to represent the value as an array and returns a mutable refference to it

fn as_object(&self) -> Option<&Self::Object>

Tries to represent the value as an object and returns a refference to it

fn as_object_mut(&mut self) -> Option<&mut Self::Object>

Tries to represent the value as an object and returns a mutable refference to it
