Struct SelectionContext 

pub struct SelectionContext {
    pub preferred_memory: MemoryDomainKind,
    pub prefer_hardware: bool,
}

What the auto-plug search optimizes for among elements that satisfy the same caps. The default (System memory, no hardware preference) reproduces a plain pipeline’s selection, so existing behavior is unchanged.

Fields

preferred_memory: MemoryDomainKind

The memory domain the consumer wants the frames in (avoids a download when it matches a producer’s CapabilityDescriptor::output_memory).

prefer_hardware: bool

Prefer a hardware path when one is available.
