Trait ExternalTextureLease 

pub trait ExternalTextureLease:
    Debug
    + Send
    + Sync
    + 'static {
    // Required method
    fn retained_bytes(&self) -> u64;

    // Provided methods
    fn prepare_submission(&self) -> bool { ... }
    fn flush_submission(&self) -> Result<(), RenderError> { ... }
    fn submitted(&self) { ... }
    fn staged_signals(&self) -> usize { ... }
}

Keeps an imported native texture and its decoder surface alive until the submission that samples it completes.

Required Methods

fn retained_bytes(&self) -> u64

Approximate native allocation bytes retained by this lease.

Provided Methods

fn prepare_submission(&self) -> bool

Stages native waits or signals on the renderer’s next queue submission.

fn flush_submission(&self) -> Result<(), RenderError>

Flushes native work staged by prepare_submission.

Errors

The frame’s error, normally RenderError::ExternalTextureSync.

fn submitted(&self)

Called right after the command buffer using the resource is submitted.

fn staged_signals(&self) -> usize

Native signals already staged on the renderer’s queue.

Staging is cleared when its submission completes, so a nonzero count when the next frame stages means a leaked signal. Read only by a debug assertion.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
