Enum ContextPlatformAttachmentReleaseError 

#[non_exhaustive]
pub enum ContextPlatformAttachmentReleaseError {
    ContextDropping,
    AttachmentInactive,
    NotPlatform,
    PlatformGenerationMismatch,
    ReleaseInProgress,
    RendererActive,
}

Failure to prepare an explicit platform attachment release.

Platform backends must complete this preflight before closing a frame, destroying native windows, or clearing callback state. The returned permit keeps the exact attachment generation reserved until the backend either commits detachment or abandons the transaction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ContextDropping

Context-owned teardown has already started.

AttachmentInactive

The supplied attachment generation has already detached.

NotPlatform

The supplied attachment does not own the platform role.

PlatformGenerationMismatch

The supplied attachment is not this Context’s active platform generation.

ReleaseInProgress

Another release transaction already reserves this platform generation.

RendererActive

Renderer resources still depend on platform-owned native handles.
