Enum CachedImageId 

Source 
pub enum CachedImageId {
    Uncached,
    NoImage,
    Image(usize),
}
Expand description

With a Cached Image ID you can track image changes. It starts with an uncached state and then gets updated with the images provided to it. It can be reset at any point in order to force a change to be detected.

Variants§

§

Uncached

The initial uncached state.

§

NoImage

The last image observed either was missing or contained no data.

§

Image(usize)

The last image had actual data and the ID stored here.

Implementations§

Source§

impl CachedImageId

Source

pub fn update_with<'i>(&mut self, image: Option<&'i Image>) -> Option<&'i [u8]>

Updates the cached image ID based on the optional image provided to this method. If a change is observed the image’s data is returned. An empty slice is returned when a transition to no image or no image data is observed.

Source

pub fn reset(&mut self)

Resets the state of the cached image ID to uncached.
