RenderTarget::TextureView missing ({texture_view:?}): make s

Error message

RenderTarget::TextureView missing ({texture_view:?}): make sure the texture view handle was not removed.

What it means

The `TextureView` variant of `MissingRenderTargetInfoError` is returned by `Camera::target_info` when the camera targets `RenderTarget::TextureView(ManualTextureViewHandle)` but the `ManualTextureViews` resource no longer contains that handle: the manual texture view was removed or never inserted.

Solutions

  1. Keep the `ManualTextureView` inserted in `ManualTextureViews` for as long as any camera targets its handle
  2. Before removing a manual view, repoint or despawn cameras referencing that handle
  3. Double-check the handle you pass equals the one used at insertion

Example fix

// before
manual_texture_views.remove(&handle); // a camera still targets RenderTarget::TextureView(handle)

// after
// first retarget/despawn cameras using `handle`, then:
manual_texture_views.remove(&handle);
Defensive patterns

Strategy: try-catch

Validate before calling

if manual_texture_views.contains_key(&handle) {
    camera.target = RenderTarget::TextureView(handle);
} else {
    warn!("manual texture view {handle:?} not inserted; not targeting it");
}

Type guard

fn texture_view_target_ready(
    handle: ManualTextureViewHandle,
    views: &ManualTextureViews,
) -> bool {
    views.contains(&handle)
}

Try / catch

match camera.target_info(windows, images, manual_texture_views) {
    Err(MissingRenderTargetInfoError::TextureView { texture_view }) => {
        warn!("manual texture view {texture_view:?} removed; skipping camera update");
    }
    other => { /* proceed */ }
}

Prevention

When it happens

Trigger: Reading camera target info while the handle used in `RenderTarget::TextureView` has been removed from `ManualTextureViews` (e.g. an external surface like a video decoder output was torn down) or the handle id never matched an inserted view.

Common situations: Removing manual texture views during shutdown or hot-reload of external surfaces without retargeting cameras; handle mismatch after re-creating manual views with different ids.
