pub struct SessionImageContext {
    pub current_images: Vec<String>,
    pub all_images: Vec<String>,
    pub image_metadata: HashMap<String, ImageMetadata>,
}

Session context for images

Fields

image_metadata: HashMap<String, ImageMetadata>

Map of image hash to metadata for quick lookup

Implementations

impl SessionImageContext

pub fn new() -> Self

pub fn has_image(&self, hash: &str) -> bool

Check if an image is in the current context

pub fn current_image_count(&self) -> usize

Get the number of current images

pub fn total_image_count(&self) -> usize

Get the total number of images ever included

pub fn clear_current(&mut self)
