atproto_codegen/lexicon

Lexicon model + JSON decoding: parse lexicon files into typed defs.

Supports record/object defs with string/integer/number/boolean/array/ref/ cid-link/bytes/blob/unknown/open-union fields. A def using anything else (e.g. token, closed unions) becomes Unsupported and is reported, not emitted wrong.

Types

Def

pub type Def {
  Record(nsid: String, properties: List(Property))
  Object(nsid: String, name: String, properties: List(Property))
  Unsupported(nsid: String, name: String, reason: String)
  Ignored
}

Constructors

Record(nsid: String, properties: List(Property))

Object(nsid: String, name: String, properties: List(Property))

Unsupported(nsid: String, name: String, reason: String)

```
Ignored
```

  TUnion(refs: List(String))
  TUnsupported(String)
}
