Struct ConnectionProperty 

pub struct ConnectionProperty {
    pub buffer: usize,
    pub valid_frame_count: u32,
    pub flags: BufferFlags,
    pub signature: u32,
}

Audio buffer descriptor handed to / from APOProcess.

Cross-platform mirror of the Windows APO_CONNECTION_PROPERTY C struct. The framework’s COM harness translates one of these per input and per output connection when dispatching into crate::ProcessingObject::process.

buffer is a raw address (usize) to match Windows’s UINT_PTR pBuffer. Higher-level code that wraps the COM harness will turn this into a typed slice; doing so here is premature because the Format negotiated between the audio engine and the APO determines the element type and layout.

signature carries the 'APOC' magic the host stamps onto every connection (see CONNECTION_PROPERTY_SIGNATURE); the harness checks it before trusting the rest of the struct.

Fields

buffer: usize

Raw address of the audio buffer (pBuffer).

valid_frame_count: u32

Number of audio frames containing valid data (u32ValidFrameCount).

flags: BufferFlags

Buffer status flags (u32BufferFlags).

signature: u32

'APOC' magic for tamper detection (u32Signature). The COM harness rejects buffers whose signature does not match CONNECTION_PROPERTY_SIGNATURE.

Implementations

impl ConnectionProperty

pub const fn empty() -> Self

Construct an empty descriptor: null buffer, zero frames, INVALID flags, and the correct signature.

Trait Implementations

impl Clone for ConnectionProperty

fn clone(&self) -> ConnectionProperty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionProperty

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

Formats the value using the given formatter.

impl PartialEq for ConnectionProperty

fn eq(&self, other: &ConnectionProperty) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
