Struct Rooted 

pub struct Rooted<S> { /* private fields */ }

A store confined to a subtree of another store.

Incoming paths are joined under root before reaching the inner store, and result paths from writes have the root stripped (component-wise) before being returned, so the root never leaks to callers. A write result that escapes the root is an error rather than a leak.

Implementations

impl<S> Rooted<S>

pub fn new(root: Path, inner: S) -> Self

Confine inner to the subtree at root.

pub fn into_inner(self) -> S

Unwrap, returning the inner store.
