Struct HostBackendInfo 

pub struct HostBackendInfo { /* private fields */ }

Stable metadata describing a host backend.

Implementations

impl HostBackendInfo

pub fn new( id: Symbol, transport: Symbol, media: StreamMedia, hardware_required: bool, ) -> Self

Builds backend metadata with bounded callbacks and no capabilities.

pub fn with_capabilities(self, capabilities: Vec<HostBackendCapability>) -> Self

Replaces the advertised capabilities.

pub fn id(&self) -> &Symbol

Returns the backend identifier symbol.

pub fn transport(&self) -> &Symbol

Returns the transport symbol.

pub fn media(&self) -> StreamMedia

Returns the backend media.

pub fn hardware_required(&self) -> bool

Returns whether opening a stream requires hardware.

pub fn callbacks_bounded(&self) -> bool

Returns whether host callbacks are bounded (non-blocking, fixed queue).

pub fn capabilities(&self) -> &[HostBackendCapability]

Returns the advertised capabilities.

pub fn card_expr(&self) -> Expr

Builds the browse card expression for this backend.

Trait Implementations

impl Clone for HostBackendInfo

fn clone(&self) -> HostBackendInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostBackendInfo

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

Formats the value using the given formatter.

impl Eq for HostBackendInfo

impl PartialEq for HostBackendInfo

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