Trait OutputParser 

pub trait OutputParser: Send + Sync {
    type Output;

    // Required methods
    fn parse(&self, text: &str) -> Result<Self::Output>;
    fn format_instructions(&self) -> String;
}

Trait for parsing structured output from LLM text responses.

Required Associated Types

type Output

The output type produced by this parser.

Required Methods

fn parse(&self, text: &str) -> Result<Self::Output>

Parse the raw LLM response text into structured output.

fn format_instructions(&self) -> String

Return format instructions to inject into the prompt.

These instructions tell the LLM how to format its response so this parser can extract structured data from it.

Dyn Compatibility

This trait is dyn compatible.

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