Struct PatternInferrer 

pub struct PatternInferrer { /* private fields */ }

The pattern inference engine.

Given one or more before/after example pairs, the inferrer derives a Pattern that captures the transformation.

Implementations

impl PatternInferrer

pub fn new(language: Box<dyn LanguageAdapter>) -> Self

Creates a new inferrer backed by the given language adapter.

pub fn infer_from_example(&self, before: &str, after: &str) -> Result<Pattern>

Infer a pattern from a single before/after example pair.

Errors

Returns CodemodError::PatternInference if the ASTs cannot be compared or no meaningful pattern can be derived.

pub fn infer_from_examples( &self, examples: &[(String, String)], ) -> Result<Pattern>

Infer a pattern from multiple before/after example pairs.

The algorithm infers a pattern from the first pair and then validates it against subsequent pairs, refining the confidence score.

Errors

Returns CodemodError::PatternInference if no consistent pattern can be derived across the supplied examples.
