ImageStore

Struct ImageStore 

Source
pub struct ImageStore { /* private fields */ }
Expand description

Storage for binary image data keyed by path.

Maps image paths (e.g. "image1.jpg") to their binary content. Used by the encoder to embed images into HWPX archives and by the decoder to extract them.

§Examples

use hwpforge_core::image::ImageStore;

let mut store = ImageStore::new();
store.insert("logo.png", vec![0x89, 0x50, 0x4E, 0x47]);
assert_eq!(store.len(), 1);
assert!(store.get("logo.png").is_some());

Implementations§

Source§

impl ImageStore

Source

pub fn new() -> Self

Creates an empty image store.

Source

pub fn insert(&mut self, key: impl Into<String>, data: Vec<u8>)

Inserts an image with the given key and binary data.

If the key already exists, the data is replaced.

Source

pub fn get(&self, key: &str) -> Option<&[u8]>

Returns the binary data for the given key, if present.

Source

pub fn len(&self) -> usize

Returns the number of stored images.

Source

pub fn is_empty(&self) -> bool

Returns true if the store contains no images.

Source

pub fn iter(&self) -> impl Iterator<Item = (&str, &[u8])>

Iterates over all (key, data) pairs.
