baml.errors.Context

The temporal context of a thrown error: the error value itself, where it was thrown, and the error it superseded while the scope was unwinding (its `cause`), if any. Bound by the second parameter of a `catch (e, ctx)` handler.

Reference version

Signature

class baml.errors.Context

The temporal context of a thrown error: the error value itself, where it was thrown, and the error it superseded while the scope was unwinding (its cause), if any. Bound by the second parameter of a catch (e, ctx) handler.

The chain runs newest → oldest through cause; root_cause walks to the original failure at the tail, and to_string renders the whole chain Python-style ("During handling of the above error, another error occurred").
