Implementations

impl CorpusService

pub fn build_index( index: &dyn CorpusIndex, corpus_dir: &Path, ) -> Result<usize, AppError>

Build the corpus index from a directory tree.

Errors

Returns AppError::Corpus on failure.

pub fn search( index: &dyn CorpusIndex, payload: &Payload, technique: StegoTechnique, max_results: usize, ) -> Result<Vec<CorpusEntry>, AppError>

Search the index for covers that best encode payload using technique.

Errors

Returns AppError::Corpus on failure.

pub fn search_for_model( index: &dyn CorpusIndex, payload: &Payload, model_id: &str, resolution: (u32, u32), max_results: usize, ) -> Result<Vec<CorpusEntry>, AppError>

Search the index restricted to a specific camera model and resolution.

Errors

Returns AppError::Corpus on failure.

pub fn model_stats(index: &dyn CorpusIndex) -> Vec<(SpectralKey, usize)>

Return per-model/resolution entry counts from the index.
