Struct lang_util::node::Node

pub struct Node<T: NodeContent> {
    pub content: T,
    pub span: Option<NodeSpan>,
}

A syntax node with span information

Fields

content: T

Contents of this syntax node

span: Option<NodeSpan>

Span in the input this node was parsed from

Implementations

impl<T: NodeContent> Node<T>

pub fn new(content: T, span: Option<NodeSpan>) -> Self

Create a new syntax node with span information

pub fn into_inner(self) -> T

Return the wrapped syntax node, discarding the span information

pub fn map<U: NodeContent>(self, f: impl FnOnce(T) -> U) -> Node<U>

Map this content of this node into a new node

pub fn map_spanned<U: NodeContent>(self, f: impl FnOnce(Self) -> U) -> Node<U>

Map this content of this node into a new node with the same span

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: NodeContent> Deref for Node<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: NodeContent> DerefMut for Node<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T: NodeContent + Display> Display for Node<T>

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

Formats the value using the given formatter.

impl<T: NodeContent> From<T> for Node<T>

fn from(inner: T) -> Self

Converts to this type from the input type.

impl<T: NodeContent + Hash> Hash for Node<T>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl<T: NodeContentDisplay + NodeContent> NodeDisplay for Node<T>

fn name() -> Option<&'static str>

Name of the syntax node’s type

fn start(&self) -> Option<TextSize>

Starting position of the node

fn end(&self) -> Option<TextSize>

Ending position of the node

fn source_id(&self) -> Option<FileId>

Source id of the node

fn display(&self) -> NodeDisplayWrapper<'_, Self>

Obtain a display wrapper for the current node

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

Display extra information for the node

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

Display the node’s children

impl<T: NodeContent + Ord> Ord for Node<T>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T: NodeContent + PartialEq> PartialEq<Node<T>> for Node<T>

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: NodeContent + PartialOrd> PartialOrd<Node<T>> for Node<T>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
