[−][src]Function ra_ap_syntax::algo::ancestors_at_offset
pub fn ancestors_at_offset(
node: &SyntaxNode,
offset: TextSize
) -> impl Iterator<Item = SyntaxNode>
Returns ancestors of the node at the offset, sorted by length. This should
do the right thing at an edge, e.g. when searching for expressions at { <|>foo }
we will get the name reference instead of the whole block, which
we would get if we just did find_token_at_offset(...).flat_map(|t| t.parent().ancestors())
.
