Struct StepImageCollection 

pub struct StepImageCollection {
    pub images: HashMap<usize, HashMap<usize, String>>,
}

Represents the complete collection of step images for a recipe.

Images are discovered based on the Cooklang naming convention:

• RecipeName.N.ext: Stored at [0][N-1] (section 0 = linear/no section)
• RecipeName.S.N.ext: Stored at [S-1][N-1] (section S, step N)

File numbering is one-indexed (Recipe.1.jpg = first step) Internal HashMap keys are zero-indexed Section 0 is reserved for linear recipes without sections.

Supported extensions: jpg, jpeg, png, webp

Fields

images: HashMap<usize, HashMap<usize, String>>

Two-dimensional map: section_index -> step_index -> image_path

• Section 0: steps for linear recipes (Recipe.N.ext stored at [0][N-1])
• Section 1+: steps within sections (Recipe.S.N.ext stored at [S-1][N-1])

HashMap keys are zero-indexed

Implementations

impl StepImageCollection

pub fn is_empty(&self) -> bool

Returns true if there are any images in the collection

pub fn count(&self) -> usize

Returns total count of all images across all sections

pub fn get(&self, section: usize, step: usize) -> Option<&String>

Gets an image for a specific section and step.

Arguments

• section - Section number (0 for linear recipes, 1+ for sectioned recipes, one-indexed for sections)
• step - One-indexed step number (1 = first step)

Returns

Image path if found, None otherwise

Examples

// Get step 3 in linear recipe (Recipe.3.jpg stored at [0][2])
let img = images.get(0, 3);

// Get section 2, step 4 (Recipe.2.4.jpg stored at [1][3])
let img = images.get(2, 4);
