Struct Object 

pub struct Object { /* private fields */ }

Represents an Object value.

Objects are cheap to clone.

Implementations

impl Object

pub fn empty() -> Self

Returns an empty object.

pub fn from_v1_metadata<N: TreeNode>( items: impl Iterator<Item = MetadataObjectItem<N>>, ) -> Self

Creates an object from an iterator of V1 AST metadata items.

pub fn ty(&self) -> Type

Gets the type of the Object value.

pub fn iter(&self) -> impl Iterator<Item = (&str, &Value)>

Iterates the members of the object.

pub fn keys(&self) -> impl Iterator<Item = &str>

Iterates the keys of the object.

pub fn values(&self) -> impl Iterator<Item = &Value>

Iterates the values of the object.

pub fn contains_key(&self, key: &str) -> bool

Determines if the object contains the given key.

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

Gets a value from the object by key.

pub fn len(&self) -> usize

Returns the number of members in the object.

pub fn is_empty(&self) -> bool

Returns true if the object has no members.
