Function parse_llm_response_with_ir 

pub fn parse_llm_response_with_ir(
    ir: &IR,
    raw_response: &str,
    target_type: &FieldType,
) -> Result<BamlValue>

Parse an LLM response using IR type definitions

This function takes a raw LLM response string and parses it into a typed BamlValue based on the IR (Intermediate Representation). It handles:

• Extracting JSON from markdown code blocks
• Lenient JSON parsing
• Type coercion (e.g., string “30” → int 30)
• Enum validation with case-insensitive matching
• Nested structure validation

Arguments

• ir - The Intermediate Representation containing type definitions
• raw_response - The raw string response from the LLM
• target_type - The expected output type to parse into

Returns

The parsed and type-coerced BamlValue

Example

use simplify_baml::*;

let ir = IR::new();
let raw_response = r#"```json
{"name": "John", "age": "30"}
```"#;

let result = parse_llm_response_with_ir(
    &ir,
    raw_response,
    &FieldType::Class("Person".to_string())
).unwrap();
