Struct ImportMap 

pub struct ImportMap {
    item_to_info_map: IndexMap<ItemInNs, (SmallVec<[ImportInfo; 1]>, IsTraitAssocItem), FxBuildHasher>,
    importables: Vec<(ItemInNs, u32)>,
    fst: Map<Vec<u8>>,
}

A map from publicly exported items to its name.

Reexports of items are taken into account.

Fields

item_to_info_map: IndexMap<ItemInNs, (SmallVec<[ImportInfo; 1]>, IsTraitAssocItem), FxBuildHasher>

Maps from ItemInNs to information of imports that bring the item into scope.

importables: Vec<(ItemInNs, u32)>

List of keys stored in Self::item_to_info_map, sorted lexicographically by their [Name]. Indexed by the values returned by running fst.

Since a name can refer to multiple items due to namespacing and import aliases, we store all items with the same name right after each other. This allows us to find all items after the fst gives us the index of the first one.

The u32 is the index into the smallvec in the value of Self::item_to_info_map.

fst: Map<Vec<u8>>
