Struct ThumbCache

pub struct ThumbCache {
    shared: Arc<(Mutex<Shared>, Condvar)>,
    textures: HashMap<u64, (TextureHandle, [u32; 2])>,
}

Fields

shared: Arc<(Mutex<Shared>, Condvar)>

textures: HashMap<u64, (TextureHandle, [u32; 2])>

egui textures for ready thumbnails, created lazily by texture() (UI thread only).

Implementations

impl ThumbCache

pub fn new(ctx: Context, backend: Backend) -> Self

pub fn set_backend(&mut self, b: Backend)

pub fn get(&mut self, path: &str, t: f64, h: u32) -> Option<Arc<Frame>>

Thumbnail frame of path at source time t, h px tall. None while computing (request queued).

pub fn texture( &mut self, ctx: &Context, path: &str, t: f64, h: u32, ) -> Option<(TextureId, [u32; 2])>

Same as get but as an egui texture (created/cached here), with its size in pixels.

pub fn clear(&mut self)

Trait Implementations

impl Drop for ThumbCache

fn drop(&mut self)

Executes the destructor for this type.
