Struct LazyPseudoDirectoryAsync 

pub struct LazyPseudoDirectoryAsync<T>(/* private fields */);

A pseudo directory that delays constructing a PseudoDirectory until a request is received.

The intended purpose of LazyPseudoDirectoryAsync is to save memory when presenting data in a filesystem structure for debug purposes. The directory should not be accessed during regular system usage otherwise no memory savings will occur.

This is functionally identical to LazyPseudoDirectory, except it is compatible with ToPseudoDirectoryAsync (i.e. directories with asynchronous initializers). As a tradeoff, any time the contents are accessed, an async lock must be acquired, which will be less performant. As such, this should only be used when needed.

Implementations
