Struct Corpus 

pub struct Corpus {
    pub name: String,
    pub root_path: PathBuf,
    pub images: Vec<CorpusImage>,
    pub metadata: CorpusMetadata,
}

A corpus of test images.

Fields

name: String

Name of the corpus.

root_path: PathBuf

Root path of the corpus.

images: Vec<CorpusImage>

Images in the corpus.

metadata: CorpusMetadata

Metadata about the corpus.

Implementations

impl Corpus

pub fn new(name: impl Into<String>, root_path: impl Into<PathBuf>) -> Self

Create a new empty corpus.

pub fn discover(path: impl AsRef<Path>) -> Result<Self>

Discover images in a directory.

Recursively scans the directory for supported image formats (PNG, JPEG, WebP, AVIF).

pub fn load(path: impl AsRef<Path>) -> Result<Self>

Load a corpus from a JSON manifest file.

pub fn save(&self, path: impl AsRef<Path>) -> Result<()>

Save the corpus to a JSON manifest file.

pub fn len(&self) -> usize

Get the number of images in the corpus.

pub fn is_empty(&self) -> bool

Check if the corpus is empty.

pub fn filter_category(&self, category: ImageCategory) -> Vec<&CorpusImage>

Filter images by category.

pub fn filter_format(&self, format: &str) -> Vec<&CorpusImage>

Filter images by format.

pub fn filter_min_size( &self, min_width: u32, min_height: u32, ) -> Vec<&CorpusImage>

Filter images by minimum dimensions.

pub fn split(&self, train_ratio: f64) -> (Vec<&CorpusImage>, Vec<&CorpusImage>)

Split the corpus into training and validation sets.

Uses a deterministic split based on checksum to ensure reproducibility.

Arguments

• train_ratio - Fraction of images to include in training set (0.0-1.0).

pub fn compute_checksums(&mut self) -> Result<usize>

Compute checksums for all images that don’t have them.

pub fn find_duplicates(&self) -> Vec<Vec<&CorpusImage>>

Find duplicate images by checksum.

pub fn update_category_counts(&mut self)

Update category counts in metadata.

pub fn stats(&self) -> CorpusStats

Get statistics about the corpus.
