Type Alias fidl_fuchsia_io::Id
source · pub type Id = u64;
Expand description
The type to identify a node, if the implementation supports some notion of unique node ID.
§Uniqueness Guarantees
A client is usually presented with a directory tree that is the result
of composing together multiple backing implementation instances. An ID
would be unique within the corresponding instance only.
Their boundaries are rather implicit on Fuchsia, as a result of
transparently-forwarding directory proxies. It could be common for a client
to observe identical Id
s when traversing a directory tree, when it
encounters nodes from different backing instances. Therefore, the ID is best
used for debugging and informational purposes.
The [fuchsia.fs/FilesystemInfo.fs_id
] field may be used to disambiguate
IDs from different backing instances.
