Crate guid [−] [src]
This crate provides a guid!
macro for expressing
GUID
structs with a convenient literal syntax. A GUID is a Windows
globally unique identifier,
usually expressed in the following format:
{6B29FC40-CA47-1067-B31D-00DD010662DA}
With this crate, a GUID can be generated with the syntax:
guid!{"6B29FC40-CA47-1067-B31D-00DD010662DA"}
Example
#[macro_use] extern crate guid; use guid::GUID; const MY_GUID: GUID = guid!{"6B29FC40-CA47-1067-B31D-00DD010662DA"}; fn main() { assert_eq!(MY_GUID.Data1, 0x6B29FC40); assert_eq!(MY_GUID.Data2, 0xCA47); assert_eq!(MY_GUID.Data3, 0x1067); assert_eq!(MY_GUID.Data4, [ 0xB3, 0x1D, 0x00, 0xDD, 0x01, 0x06, 0x62, 0xDA ]); }
The GUID
type is re-exported from the winapi crate,
and is only available in Windows. The guid!
macro is also only available in Windows.
This crate also provides a parser, which can be used to parse GUID strings at runtime.
The parser is only available to generate an array of bytes on non-Windows platforms.
In Windows, this crate defines a parser that produces a GUID
struct.
Compatibility
This crate supports all versions of Rust (stable and nightly) starting with Rust 1.15.
