    pub(crate) type FeatureMap = BTreeMap<String, Vec<String>>;

## Aliased Type§

    struct FeatureMap {
        root: Option<NodeRef<Owned, String, Vec<String>, LeafOrInternal>>,
        length: usize,
        pub(super) alloc: ManuallyDrop<Global>,
        _marker: PhantomData<Box<(String, Vec<String>)>>,
    }

## Fields§

§`root: Option<NodeRef<Owned, String, Vec<String>, LeafOrInternal>>`§`length: usize`§`alloc: ManuallyDrop<Global>`§`_marker: PhantomData<Box<(String, Vec<String>)>>`

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
