Struct DirSlot

pub struct DirSlot(Option<MaybeUninit<vfs_DIR>>, PhantomPinned);

Available on riot_module_vfs only.

A place where a Dir can be stored

See Dir::open() for why this is necessary.

As for its implementation, this is built from an Option rather than a bare MaybeUninit because if the created Dir is leaked and then the DirSlot is dropped, the DirSlot needs to know whether or not to do any cleanup.

Invariants

This module maintains that the MaybeUninit is always initialized outside of its own functions, and that no panicking functions are called while it is uninit.

Tuple Fields

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.
