Struct sycamore::noderef::NodeRef

pub struct NodeRef<G: GenericNode>(_);

A reference to a GenericNode.

Implementations

impl<G: GenericNode + Any> NodeRef<G>

pub fn new() -> Self

Creates an empty NodeRef.

pub fn get<T: GenericNode>(&self) -> T

Gets the T stored inside the NodeRef.

Panics

Panics if the NodeRef is not set yet or is the wrong type.

For a non panicking version, see NodeRef::try_get.

pub fn try_get<T: GenericNode>(&self) -> Option<T>

Tries to get the T stored inside the NodeRef or None if it is not yet set or the wrong type.

For a panicking version, see NodeRef::get.

pub fn get_raw(&self) -> G

Gets the raw GenericNode stored inside the NodeRef.

Panics

Panics if the NodeRef is not set yet.

For a non panicking version, see NodeRef::try_get_raw.

pub fn try_get_raw(&self) -> Option<G>

Tries to get the raw GenericNode stored inside the NodeRef or None if it is not yet set.

For a panicking version, see NodeRef::get.

pub fn set(&self, node: G)

Sets the NodeRef with the specified GenericNode.

Trait Implementations

impl<G: Clone + GenericNode> Clone for NodeRef<G>

fn clone(&self) -> NodeRef<G>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<G: GenericNode> Debug for NodeRef<G>

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

Formats the value using the given formatter.

impl<G: GenericNode> Default for NodeRef<G>

fn default() -> Self

Returns the “default value” for a type.

impl<G: PartialEq + GenericNode> PartialEq<NodeRef<G>> for NodeRef<G>

fn eq(&self, other: &NodeRef<G>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &NodeRef<G>) -> bool
