Trait uefi::data_types::Identify [−][src]
Expand description
Several entities in the UEFI specification can be referred to by their GUID, this trait is a building block to interface them in uefi-rs.
You should never need to use the Identify trait directly, but instead go
for more specific traits such as Protocol or FileProtocolInfo, which
indicate in which circumstances an Identify-tagged type should be used.
Implementing Identify is unsafe because attaching an incorrect GUID to a
type can lead to type unsafety on both the Rust and UEFI side.
You can derive Identify for a type using the unsafe_guid procedural
macro, which is exported by this module. This macro mostly works like a
custom derive, but also supports type aliases. It takes a GUID in canonical
textual format as an argument, and is used in the following way:
#[unsafe_guid("12345678-9abc-def0-1234-56789abcdef0")] type Emptiness = ();
