Macro uuid 

macro_rules! uuid {
    ($uuid:expr) => { ... };
}

Parse Uuids from string literals at compile time.

Usage

This macro transforms the string literal representation of a Uuid into the bytes representation, raising a compilation error if it cannot properly be parsed.

Examples

Setting a global constant:

pub const SCHEMA_ATTR_CLASS: Uuid = uuid!("00000000-0000-0000-0000-ffff00000000");
pub const SCHEMA_ATTR_UUID: Uuid = uuid!("00000000-0000-0000-0000-ffff00000001");
pub const SCHEMA_ATTR_NAME: Uuid = uuid!("00000000-0000-0000-0000-ffff00000002");

Defining a local variable:

let uuid = uuid!("urn:uuid:F9168C5E-CEB2-4faa-B6BF-329BF39FA1E4");

Using a const variable:

const UUID_STR: &str = "12345678-1234-5678-1234-567812345678";
let UUID = uuid!(UUID_STR);
