error schema-attr

Некорректный атрибут сериализации (@tag, @v, @since, @removed, @renamed, @zigzag, @repr, @codec).

What it means#

An attribute of the serialization schema is malformed or used in the wrong place:

• @tag(n) needs a number in 1..536870911 outside protobuf's reserved range 19000..19999, unique within the type, and not a tag reserved by @removed;
• @v(n) and @since(n) need a version >= 1;
• @removed(N, "member") is written on the type (D-2108), names a member that no longer exists, and optionally tag: T;
• @renamed(from: "old") needs the old name;
• @zigzag applies to integer fields and types;
• @repr(W) needs impl Repr<W> for T; @codec(C) / @codec(json: C1, oxl: C2) need codec types with impl Codec<T> for C.

Example#

data Order {
  @tag(1) id: i64
  @tag(1) total: i64      // <- schema-attr
}

schema-attr

How to fix#

Give every field its own tag or drop the explicit tags and let the compiler assign them (the assignment is recorded in oxl.schema.lock). For a removed field keep the type attribute @removed(2, "total") instead of reusing the number.
