Progressive image loader

Implementations

impl ProgressiveLoader

pub fn new(max_cached_images: usize) -> Self

Create a new progressive loader

pub fn load( &self, request: &LoadRequest, raw_data: Option<&[u8]>, width: usize, height: usize, bits_per_pixel: usize, ) -> LoadResult

Load an image progressively

Returns immediately with best available quality. Schedules background load for higher quality if needed.

pub fn store_thumbnail( &self, study_id: &str, series_id: &str, slice_index: usize, data: Vec<u8>, original_size: [usize; 2], )

Store thumbnail only (for quick initial display)

pub fn store_mid_res( &self, study_id: &str, series_id: &str, slice_index: usize, data: Vec<u8>, original_size: [usize; 2], )

Store mid-res image

pub fn store_full_res( &self, study_id: &str, series_id: &str, slice_index: usize, data: Vec<u8>, original_size: [usize; 2], )

Store full-res image

pub fn get_quality_status( &self, study_id: &str, series_id: &str, slice_index: usize, ) -> Option<QualityStatus>

Get quality status for a slice

pub fn get_series_quality( &self, study_id: &str, series_id: &str, ) -> Vec<QualityStatus>

Get all quality statuses for a series

pub fn clear_study(&self, study_id: &str)

Clear cache for a specific study

pub fn clear(&self)

Clear entire cache

pub fn stats(&self) -> ProgressiveLoaderStats

Get cache statistics
