Implementations

impl Value

pub fn is_null(&self) -> bool

Returns true if the value is null.

pub fn is_bool(&self) -> bool

Returns true if the value is a boolean.

pub fn is_number(&self) -> bool

Returns true if the value is a number.

pub fn is_string(&self) -> bool

Returns true if the value is a string.

pub fn is_array(&self) -> bool

Returns true if the value is an array.

pub fn is_object(&self) -> bool

Returns true if the value is an object.

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

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

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

If the value is a number, tries to return it as an i64. Returns None if the value is not a number or cannot be represented as i64.

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

If the value is a number, returns it as an f64. Returns None if the value is not a number.

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

If the value is a string, returns the associated str. Returns None otherwise.

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

If the value is an array, returns a reference to the associated vector. Returns None otherwise.

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

If the value is an object, returns a reference to the associated map. Returns None otherwise.
