Struct ElementDesc 

pub struct ElementDesc {
    pub name: &'static str,
    pub templates: Vec<PadTemplate>,
    pub capabilities: CapabilityDescriptor,
}

An element type’s autoplug-relevant metadata: a display name and its static pad templates (typically <E as PadTemplates>::pad_templates()). The search reads only the first sink and first source template; multi-pad elements (tees, muxers) are not auto-plug candidates and are simply never matched.

Fields

name: &'static str

Human-readable type name, used to report the chosen chain.

templates: Vec<PadTemplate>

The element type’s pad templates, in declaration order.

capabilities: CapabilityDescriptor

Auto-plug selection signals (output memory, hardware, rank): how the search picks this among elements satisfying the same caps. See CapabilityDescriptor.

Implementations

impl ElementDesc

pub fn new(name: &'static str, templates: Vec<PadTemplate>) -> Self

Build a descriptor from a name and its pad templates. The capabilities default (software, System memory, rank 0); tag a GPU / hardware producer with the builders below.

pub fn with_output_memory(self, kind: MemoryDomainKind) -> Self

Tag the memory feature this element’s source pad produces. Builder form.

pub fn with_acceleration(self, acceleration: Acceleration) -> Self

Tag this element’s path as hardware-accelerated. Builder form.

pub fn with_rank(self, rank: i16) -> Self

Set the deterministic tiebreaker rank (higher wins among equal scores).

pub fn output_memory(&self) -> MemoryDomainKind

The memory feature the element’s source pad emits.

Trait Implementations

impl Clone for ElementDesc

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ElementDesc

fn fmt(&self, f: &mut Formatter<'_>) -> Result
