Enum Event 

pub enum Event {
    NodeStarted {
        kind: SyntaxKind,
        forward_parent: Option<usize>,
    },
    NodeFinished,
    Token {
        kind: SyntaxKind,
        span: Span,
    },
}

Represents an event produced by the parser.

The parser produces a stream of events that can be used to construct a CST.

Variants

NodeStarted

A new node has started.

Fields

kind: SyntaxKind

The kind of the node.

forward_parent: Option<usize>

For left-recursive syntactic constructs, the parser produces a child node before it sees a parent. forward_parent saves the position of current event’s parent.

NodeFinished

A node has finished.

Token

A token was encountered.

Fields

kind: SyntaxKind

The syntax kind of the token.

span: Span

The source span of the token.

Implementations

impl Event

pub fn abandoned() -> Self

Gets an start node event for an abandoned node.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl PartialEq for Event

fn eq(&self, other: &Event) -> 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 Eq for Event

impl StructuralPartialEq for Event
