Struct DirEntry 

Source 
pub struct DirEntry { /* private fields */ }
Expand description

DirEntry is a [Capability] that’s a thin wrapper over vfs::directory::entry::DirectoryEntry When externalized to FIDL, a DirEntry becomes an opaque eventpair token. This means that external users can delegate DirEntrys and put them in [Dict]s, but they cannot create their own.

The [Capability::try_into_directory_entry] implementation simply extracts the inner vfs::directory::entry::DirectoryEntry object.

DirEntry is a stopgap for representing CF capabilities that don’t have a natural bedrock representation yet. https://fxbug.dev/340891837 tracks its planned deletion.

When built for host, DirEntry is an empty placeholder type, as vfs is not supported on host.
