Trait TextModelExt

}

Structured output on any TextModel (issue #580). Blanket-implemented for every TextModel, so an adapter cannot override — and cannot skip — the schema check, the validation, or the repair retry; import the trait to call the methods.

Required Methods

fn complete_json<'life0, 'life1, 'async_trait>( &'life0 self, prompt: Prompt, schema: &'life1 Schema, ) -> Pin<Box<dyn Future<Output = Result<Value, TextModelError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Completes prompt and returns a value that conforms to schema.

The schema is checked on the supported subset before the first call, the prompt’s Prompt::json_schema is set to it, and the answer — native structured output, or text parsed as JSON — is validated against it. On failure the model gets one repair retry; a second failure is TextModelError::SchemaViolation.

Errors

• TextModelError::InvalidSchema if schema uses a keyword the validator does not implement; the model is never called.
• TextModelError::SchemaViolation if the answer still does not conform after the repair retry. The message names the failed path and reason only, never the model’s output.
• Whatever complete itself returned, unchanged: NotConfigured, Rejected, Transient, Transport, Unsupported.

fn complete_as<'life0, 'async_trait, T>( &'life0 self, prompt: Prompt, ) -> Pin<Box<dyn Future<Output = Result<T, TextModelError>> + Send + 'async_trait>>

where T: JsonSchema + DeserializeOwned + Send + 'async_trait, Self: 'async_trait, 'life0: 'async_trait,

Completes prompt and deserializes the conforming value into T, using T’s own schema (schema_for) as the constraint — the typed form of TextModelExt::complete_json.

Errors

The same as TextModelExt::complete_json, plus TextModelError::SchemaViolation if the conforming value does not deserialize into T (a shape the schema generator and the deserializer disagree on).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
