Struct Metadata 

pub struct Metadata<'a> {
    pub span: Span<'a>,
}

Metadata for a given syntax token.

This includes the Span of the token. With the lossless feature, Metadata also includes non_trivia, which stores non-trivia tokens such as whitespace and comments

Fields

span: Span<'a>

Implementations

impl<'a> Metadata<'a>

pub fn new(span: Span<'a>, _: Vec<NonTriviaToken<'a>>) -> Self

Construct a new Metadata. If the lossless feature isn’t enabled, non_trivia is discarded.

Trait Implementations

impl<'a> Clone for Metadata<'a>

fn clone(&self) -> Metadata<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Metadata<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Metadata<'a>

fn default() -> Metadata<'a>

Returns the “default value” for a type.

impl<'a, 'b> IntoIterator for &'b Metadata<'a>

type Item = Node<'a, 'b>

The type of the elements being iterated over.

type IntoIter = Empty<Node<'a, 'b>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a, 'b> IntoIterator for &'b mut Metadata<'a>

type Item = Node<'a, 'b>

The type of the elements being iterated over.

type IntoIter = Empty<Node<'a, 'b>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a: 'b, 'b> Nodes<'a, 'b> for Metadata<'a>

fn nodes(&self) -> NodeIter<'a, 'b>

The nodes of the object

fn add_nodes(&'b self, _: &mut Vec<Node<'a, 'b>>, _: fn(Node<'a, 'b>) -> bool)

Add all children nodes satisfying the given predicate to the provided Vec

fn find(&'b self, pred: fn(Node<'a, 'b>) -> bool) -> Vec<Node<'a, 'b>>

Find all children nodes satisfying the given predicate

impl<'a> PartialEq for Metadata<'a>

fn eq(&self, _: &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.
