Struct ItemTree 

pub struct ItemTree {
    top_level: Box<[ModItemId]>,
    attrs: ThinVec<(ModItemId, AttrsOrCfg)>,
    vis: ItemVisibilities,
    big_data: ThinVec<(FileAstId<Item>, BigModItem)>,
    small_data: ThinVec<(FileAstId<Item>, SmallModItem)>,
}

The item tree of a source file.

Fields

top_level: Box<[ModItemId]>

attrs: ThinVec<(ModItemId, AttrsOrCfg)>

Sorted by the id. The last item, if it has ModItemId::TOP_OWNER, is the top level attrs.

vis: ItemVisibilities

big_data: ThinVec<(FileAstId<Item>, BigModItem)>

small_data: ThinVec<(FileAstId<Item>, SmallModItem)>

Implementations

impl ItemTree

pub(crate) fn top_level_items(&self) -> &[ModItemId]

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

pub(crate) fn top_level_attrs(&self) -> Option<&AttrsOrCfg>

Returns the inner attributes of the source file.

pub(crate) fn attrs(&self, of: ModItemId) -> Option<&AttrsOrCfg>

pub fn item_tree_stats(&self) -> ItemTreeDataStats

Returns a count of a few, expensive items.

For more detail, see ItemTreeDataStats.
