Struct SyntaxToken 

pub struct SyntaxToken { /* private fields */ }

A leaf token in the syntax tree.

Represents a contiguous span of source text with a known kind.

Implementations

impl SyntaxToken

pub fn new(kind: SyntaxKind, range: TextRange) -> Self

Creates a new token with the given kind and range.

pub fn kind(&self) -> SyntaxKind

The kind of this token.

pub fn range(&self) -> TextRange

The source range of this token.

pub fn is_missing(&self) -> bool

Whether this token is missing from the source (zero-length placeholder).

A missing token marks the exact offset where the absent element would be inserted — the edit API’s insertion anchor (see the module docs). Placeholders are only ever replaced by a real token, never extended in place.

pub fn text<'a>(&self, source: &'a str) -> &'a str

Extract the corresponding text slice from source.

pub fn pretty_fmt(&self, src: &str, indent: usize, out: &mut String)

Write a pretty-printed token line.

A zero-length (missing placeholder) token renders as <missing> instead of an empty text literal.
