Struct CotParser 

pub struct CotParser;

Parses chain-of-thought responses into structured ThoughtSteps.

Implementations

impl CotParser

pub fn new() -> Self

Create a new parser.

pub fn parse_steps(&self, response: &str) -> Vec<ThoughtStep>

Extract numbered steps from a response.

Recognises lines of the form:

Step N: <thought> -> <conclusion>
Step N: <thought> → <conclusion>

If no arrow separator is present the entire text is treated as the thought and the conclusion is left empty.

pub fn extract_final_answer(&self, response: &str) -> String

Extract the final answer from a response.

Looks for lines beginning with Therefore:, Answer:, or Conclusion: (case-insensitive) and returns the text that follows. If none is found, returns an empty string.

pub fn compute_confidence(&self, steps: &[ThoughtStep]) -> f64

Compute average confidence across all steps.

Heuristic: longer thought text implies more thorough reasoning, which maps to a higher confidence, capped at 1.0.

pub fn parse(&self, response: &str) -> ChainOfThought

Convenience: parse steps and final answer, then produce a full ChainOfThought.
