Struct apollo_compiler :: Node Copy item path

impl<T> Node<T>

pub fn new_parsed(node: T, location: NodeLocation) -> Self

Create a new Node for something parsed from the given source location

pub fn new(node: T) -> Self

Create a new Node for something created programatically, not parsed from a source file

pub fn location(&self) -> Option<NodeLocation>

pub fn is_built_in(&self) -> bool

Whether this node is located in FileId::BUILT_IN, which defines built-in directives, built-in scalars, and introspection types.

pub fn line_column(&self, sources: &SourceMap) -> Option<GraphQLLocation>

If this node contains a location, convert it to line and column numbers

pub fn same_location(&self, node: U) -> Node

Returns the given node at the same location as self (e.g. for a type conversion).

pub fn to_component(&self, origin: ComponentOrigin) -> Component<T>

pub fn ptr_eq(&self, other: &Self) -> bool

Returns whether two Nodes point to the same memory allocation

pub fn make_mut(&mut self) -> &mut T
where T: Clone,

Returns a mutable reference to T, cloning it if necessary

This is functionally equivalent to Arc::make_mut from the standard library.

If this Node is uniquely owned, make_mut() will provide a mutable reference to the contents. If not, make_mut() will create a new Node with a clone of the contents, update self to point to it, and provide a mutable reference to its contents.

This is useful for implementing copy-on-write schemes where you wish to avoid copying things if your Node is not shared.

pub fn get_mut(&mut self) -> Option<&mut T>

Returns a mutable reference to T if this Node is uniquely owned
