Struct ra_ap_hir_def::item_tree::ItemTree

pub struct ItemTree { /* fields omitted */ }

The item tree of a source file.

Implementations

impl ItemTree

pub fn item_tree_query(
    db: &dyn DefDatabase,
    file_id: HirFileId
) -> Arc<ItemTree>

pub fn top_level_items(&self) -> &[ModItem]

Returns an iterator over all items located at the top level of the HirFileId this ItemTree was created from.

pub fn top_level_attrs(&self) -> &Attrs

Returns the inner attributes of the source file.

pub fn attrs(&self, of: AttrOwner) -> &Attrs

pub fn inner_items(&self, ast: FileAstId<Item>) -> &[ModItem]

Returns the lowered inner items that ast corresponds to.

Most AST items are lowered to a single ModItem, but some (eg. use items) may be lowered to multiple items in the ItemTree.

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

pub fn source<S: ItemTreeNode>(
    &self,
    db: &dyn DefDatabase,
    of: ItemTreeId<S>
) -> S::Source
