Attribute Macro uuid_enum 

#[uuid_enum]

Attribute macro for UUID-backed enums.

Usage:

use uuid_enum::uuid_enum;

#[uuid_enum]
pub enum AccountGrant {
    #[uuid("bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb")]
    Owner,
    #[uuid("cccccccc-cccc-cccc-cccc-cccccccccccc")]
    Manage,
}

This expands to a #[repr(u128)] enum where each variant’s discriminant is the numerical u128 value of its UUID. It also generates:

• const ALL: &'static [Self] containing all variants
• pub const fn as_u128(self) -> u128
• pub const fn from_u128(raw: u128) -> Option<Self>
• pub const fn to_uuid(self) -> ::uuid_enum::uuid::Uuid
• pub const fn from_uuid(id: ::uuid_enum::uuid::Uuid) -> Option<Self>

The UUID values are checked for global uniqueness across the crate. Reuse of the same UUID in two variants (even in different enums using this macro) is a compile error.
