Module std.reflection

import std.reflection;

Public declaration contracts and authored examples. A page can document several related symbols. Implementation bodies are excluded.

StableId

pub attribute StableId

Overrides the canonical nominal StableTypeId with one UUID.

The lowercase normal-form UUID must be unique in the linked reflection registry; changing it is an explicit metadata compatibility break.

Example

module example.stable_id;
import std.reflection as reflection;
[reflection.StableId("2f5f7f70-83d2-4f03-9f0c-3bf895eebfd1")]
pub struct Packet { pub Code: u32; }
fn Main() -> i32 {
    let Descriptor = reflection.TypeOf<Packet>();
    if Descriptor.StableId == default(reflection.StableTypeId) { return 1; }
    return 0;
}

StableId.Value

pub Value: str;

Stores the exact authored canonical UUID string.
