Windows GUID/CLSID/IID string and binary serialization

Guid transparently wraps GUID.

Implements Display and FromStr string conversion, also Hash and Eq.

Curly braces ({}) are optional for FromStr.

serde

Use the guid_serde feature to derive Serialize and Deserialize, you can then derive them for structs containing GUID like so:

# fn main() {}
#
# #[cfg(feature = "guid_serde")]
# extern crate serde_derive;
# extern crate winapi;
#
# #[cfg(feature = "guid_serde")]
# mod test {
use guid_win::GUIDSerde;
use serde_derive::{Deserialize, Serialize};
use winapi::shared::guiddef::GUID;

#[derive(Serialize, Deserialize)]
struct SerdeTest {
#[serde(with = "GUIDSerde")]
guid: GUID,
}
# }
