Enum FormatNegotiation 

pub enum FormatNegotiation {
    Accept,
    Suggest(StreamFormat),
    Reject,
}

The outcome of a stream-format negotiation.

Mirrors the three ways an AudioServerPlugin can answer the HAL’s “can you do this format?” query (AudioServerPlugInDriverInterface::GetPropertyData over kAudioStreamPropertyAvailableVirtualFormats and the format setters):

• Self::Accept — the proposed format is supported as-is.
• Self::Suggest — the proposed format is not supported, but the named alternative is the closest one that is.
• Self::Reject — the format is not supported and there is no sensible alternative to offer.

Variants

Accept

The proposed format is supported; adopt it unchanged.

Suggest(StreamFormat)

The proposed format is not supported; this alternative is.

Reject

The proposed format is not supported and no alternative is offered.

Trait Implementations

impl Clone for FormatNegotiation

fn clone(&self) -> FormatNegotiation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatNegotiation

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

Formats the value using the given formatter.

impl PartialEq for FormatNegotiation

fn eq(&self, other: &FormatNegotiation) -> 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.
