Struct Object

pub struct Object(pub HashMap<String, Value>);

Represents a simple object that can be used to store key-value pairs.

Tuple Fields

0: HashMap<String, Value>

Implementations

impl Object

pub fn new() -> Self

Creates a new Object.

pub fn get(&self, key: &str) -> Option<&Value>

Gets the value associated with the given key.

pub fn set<T: Into<String>, V: Into<Value>>( &mut self, key: T, value: V, ) -> Option<Value>

Sets the value for the given key.

If the object didn’t have this key present, None is returned.

If the object did have this key present, the value is updated, and the old value is returned. The key should be a string and the value should be convertible to a Value.

pub fn is_empty(&self) -> bool

Checks if the object is empty, i.e. has no key-value pairs.

pub fn size(&self) -> usize

Returns the number of key-value pairs in the object.

Trait Implementations

impl Clone for Object

fn clone(&self) -> Object

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Object

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

Formats the value using the given formatter.

impl From<Object> for Value

fn from(o: Object) -> Self

Converts to this type from the input type.

impl FromIterator<(String, Value)> for Object

fn from_iter<T: IntoIterator<Item = (String, Value)>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for Object

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