Struct JsonishParser 

pub struct JsonishParser { /* private fields */ }

Three-phase JSON parser for malformed LLM outputs.

Phases

1. Strip & Fix: Quick string transformations
2. Standard Parse: Attempt serde_json::from_str (fast path)
3. Lenient Parse: State machine for incomplete/malformed JSON

Example

use simple_agents_healing::parser::JsonishParser;

let parser = JsonishParser::new();
let result = parser.parse(r#"{"key": "value",}"#).unwrap();
assert!(result.flags.iter().any(|f| matches!(f,
    simple_agent_type::coercion::CoercionFlag::FixedTrailingComma)));

Implementations

impl JsonishParser

pub fn new() -> Self

Create a new parser with default configuration.

pub fn with_config(config: ParserConfig) -> Self

Create a parser with custom configuration.

pub fn parse(&self, input: &str) -> Result<ParserResult>

Parse potentially malformed JSON.

Returns a ParserResult containing the parsed value, flags indicating transformations applied, and a confidence score.

Errors

Returns HealingError::ParseFailed if all parsing phases fail. Returns HealingError::LowConfidence if confidence is below threshold.

Example

use simple_agents_healing::parser::JsonishParser;

let parser = JsonishParser::new();

// Perfect JSON - no healing needed
let result = parser.parse(r#"{"key": "value"}"#).unwrap();
assert_eq!(result.confidence, 1.0);
assert!(result.flags.is_empty());

// Malformed JSON - healing applied
let result = parser.parse(r#"{"key": "value",}"#).unwrap();
assert!(result.confidence < 1.0);
assert!(!result.flags.is_empty());

Trait Implementations

impl Debug for JsonishParser

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JsonishParser

fn default() -> Self

Returns the “default value” for a type.
