Struct NlConfigGenerator 

pub struct NlConfigGenerator;

Generates YAML configuration from natural language descriptions.

The generator uses a two-phase approach:

1. Parse the natural language description into a structured ConfigIntent.
2. Map the intent to a YAML configuration string using preset templates.

Implementations

impl NlConfigGenerator

pub fn generate( description: &str, provider: &dyn LlmProvider, ) -> Result<String, SynthError>

Generate a YAML configuration from a natural language description.

Uses the provided LLM provider to help parse the description, with keyword-based fallback parsing for reliability.

Errors

Returns SynthError::GenerationError if the description cannot be parsed or the resulting configuration is invalid.

pub fn parse_intent( description: &str, provider: &dyn LlmProvider, ) -> Result<ConfigIntent, SynthError>

Parse a natural language description into a structured ConfigIntent.

Attempts to use the LLM provider first, then falls back to keyword-based extraction for reliability.

pub fn generate_full( description: &str, provider: &dyn LlmProvider, ) -> Result<String, SynthError>

Generate a complete YAML configuration from a natural language description.

Unlike generate, which maps to a template via structured intent, this method asks the LLM to produce the full YAML directly using the complete DataSynth config schema as guidance. Falls back to generate if the LLM response is not valid YAML or does not contain expected top-level keys.

pub fn extract_yaml(content: &str) -> String

Extract YAML content from an LLM response, stripping ``` fences if present.

pub fn full_schema_system_prompt() -> String

System prompt describing the full DataSynth configuration schema.

Used by generate_full so the LLM can produce a complete config.

pub fn intent_to_yaml(intent: &ConfigIntent) -> Result<String, SynthError>

Map a ConfigIntent to a YAML configuration string.
