Struct Value 

pub struct Value { /* private fields */ }

A value read from the input.

This can be any of the following types:

• boolean
• number
• string
• null
• object
• array
• error

Implementations

impl Value

pub fn intern_utf8_str(&self, s: &str) -> InternedStringId

Intern a string. This is just a convenience method equivalent to calling Context::intern_utf8_str, if you don’t have a Context easily accessible.

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

Get the value as a boolean, if it is one.

pub fn is_null(&self) -> bool

Check if the value is null.

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

Get the value as a number, if it is one. Note that this will apply to both integers and floats.

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

Get the value as a string, if it is one.

pub fn is_obj(&self) -> bool

Check if the value is an object.

pub fn get_obj_prop(&self, prop: &str) -> Self

Get a property from the object.

pub fn get_interned_obj_prop( &self, interned_string_id: InternedStringId, ) -> Self

Get a property from the object by its interned string ID.

pub fn is_array(&self) -> bool

Check if the value is an array.

pub fn array_len(&self) -> Option<usize>

Get the length of the array, if it is one.

pub fn obj_len(&self) -> Option<usize>

Get the length of the object, if it is one.

pub fn get_at_index(&self, index: usize) -> Self

Get an element from the array or object by its index.

pub fn get_obj_key_at_index(&self, index: usize) -> Option<String>

Get the key of an object by its index.

pub fn as_error(&self) -> Option<ErrorCode>

Get the error code, if it is one.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
