Type Alias TokenTreesView

pub type TokenTreesView<'a> = TokenTreesView<'a, SpanData<SyntaxContext>>;

Aliased Type

struct TokenTreesView<'a>(/* private fields */);

Implementations

impl<'a, S> TokenTreesView<'a, S>

where S: Copy,

pub fn new(tts: &'a [TokenTree<S>]) -> TokenTreesView<'a, S>

pub fn iter(&self) -> TtIter<'a, S>

pub fn cursor(&self) -> Cursor<'a, S>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn try_into_subtree(self) -> Option<SubtreeView<'a, S>>

pub fn strip_invisible(self) -> TokenTreesView<'a, S>

pub fn flat_tokens(&self) -> &'a [TokenTree<S>]

This returns a flat structure of tokens (subtrees will be represented by a single node preceding their children), so it isn’t suited for most use cases, only for matching leaves at the beginning/end with no subtrees before them. If you need a structured pass, use [TtIter].

pub fn split( self, split_fn: impl FnMut(TtElement<'a, S>) -> bool, ) -> impl Iterator<Item = TokenTreesView<'a, S>>
