Struct StructuredOutputParser 

pub struct StructuredOutputParser<T: DeserializeOwned> { /* private fields */ }

Parser that deserialises JSON text to a typed struct.

Use this when you have a specific Rust type annotated with #[derive(Deserialize)] that you want to parse model output into.

Examples

use serde::Deserialize;
use synwire_core::output_parsers::{OutputParser, StructuredOutputParser};

#[derive(Deserialize, Debug, PartialEq)]
struct Person {
    name: String,
    age: u32,
}

let parser = StructuredOutputParser::<Person>::new();
let result = parser.parse(r#"{"name": "Alice", "age": 30}"#).unwrap();
assert_eq!(result.name, "Alice");
assert_eq!(result.age, 30);

Implementations

impl<T: DeserializeOwned> StructuredOutputParser<T>

pub const fn new() -> Self

Create a new structured output parser.

impl<T: DeserializeOwned + Send + Sync> StructuredOutputParser<T>

pub fn parse_with_retry_context( &self, text: &str, ) -> Result<T, (SynwireError, String)>

Parse with a validation error message for retry.

On success, returns the parsed value. On failure, returns both the original error and a formatted context string suitable for inclusion in a retry prompt.

Errors

Returns a tuple of (SynwireError, retry context String) when parsing fails.

Trait Implementations

impl<T: DeserializeOwned> Default for StructuredOutputParser<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: DeserializeOwned + Send + Sync> OutputParser for StructuredOutputParser<T>

type Output = T

The output type this parser produces.

fn parse(&self, text: &str) -> Result<T, SynwireError>

Parse raw text output from a model.

fn get_format_instructions(&self) -> String

Get format instructions to include in prompts.
