Struct UseTree 

pub struct UseTree { /* private fields */ }

Implementations

impl UseTree

pub fn path_segments(&self) -> impl Iterator<Item = SyntaxToken> + '_

The leading dotted/::-separated path segments, in order — use_tree’s grammar lays these out as bare IDENT tokens interspersed with :: directly inside USE_TREE (no nested PATH node, unlike import’s path), so this walks direct-child tokens up to (not including) an as-alias or a nested { … } list.

pub fn alias_token(&self) -> Option<SyntaxToken>

The as alias name, if this tree ends in one.

pub fn nested_list(&self) -> Option<UseTreeList>

The nested { a, b as c, … } group, if this tree has one.
