Struct Node 

pub struct Node<T> { /* private fields */ }

A wrapper type for a node, containing span details of that given node as it relates to the source input from which the node was generated.

Implementations

impl<T> Node<T>

pub fn map<R>(self, f: impl FnMut(T) -> R) -> Node<R>

pub fn map_option<R>(self, f: impl FnMut(T) -> Option<R>) -> Option<Node<R>>

pub fn new(span: Span, node: T) -> Self

pub fn span(&self) -> Span

Get a copy of the Span of the node.

pub fn start(&self) -> usize

Get the starting byte of the node within the input source.

pub fn end(&self) -> usize

Get the ending byte of the node within the input source.

pub fn inner(&self) -> &T

Get a reference to the inner node type T.

pub fn take(self) -> (Span, T)

pub fn into_inner(self) -> T

Consume the node, and get the inner node type T.

pub fn into_spanned(self) -> (usize, T, usize)

Consume the node and return a tuple consisting of the start, node type T and the end position.

pub fn as_deref(&self) -> &T::Target

where T: Deref,

Trait Implementations

impl<T> AsRef<T> for Node<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for Node<T>

fn clone(&self) -> Node<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Node<T>

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

Formats the value using the given formatter.

impl<T> Deref for Node<T>

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

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

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

Formats the value using the given formatter.

impl FromIterator<Node<Expr>> for Array

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = Node<Expr>>,

Creates a value from an iterator.

impl<T: 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, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

fn cmp(&self, other: &Node<T>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

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

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

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

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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