Enum StreamCapability 

pub enum StreamCapability {
    Exact,
    Deterministic,
    Realtime,
    Bounded,
    Remote,
    Replayable,
    Preview,
    Persistent,
    Resumable,
    Lossy,
}

One thing a transport is permitted to do with a stream.

A TransportProfile carries a set of these. The kernel defines the capability vocabulary as Symbols; this enum is the concrete set the fabric recognizes, mapped under the stream/capability namespace.

Variants

Exact

Sample-exact delivery with no approximation.

Deterministic

Deterministic, reproducible output for identical input.

Realtime

Real-time delivery.

Bounded

Bounded buffering and latency.

Remote

Delivery across a remote (networked) link.

Replayable

Output that can be replayed from a recorded source.

Preview

Lower-fidelity preview output.

Persistent

Output backed by persistent storage.

Resumable

Delivery that can resume after interruption.

Lossy

Lossy delivery that may drop or approximate data.

Implementations

impl StreamCapability

pub fn wire_label(self) -> &'static str

Returns the stable wire label for this capability (for example "realtime").

pub fn symbol(self) -> Symbol

Returns the kernel Symbol for this capability under the stream/capability namespace.

pub fn from_symbol(symbol: &Symbol) -> Result<Self>

Parses a StreamCapability from a kernel Symbol.

Accepts the bare label and the fully qualified stream/capability/<label> form, erroring on any unrecognized capability.

pub fn latency_class(self) -> LatencyClass

Returns the latency class this capability implies on its own.

Used as a default when reasoning about a lone capability; an assembled TransportProfile carries its own LatencyClass independently.

Trait Implementations

impl Clone for StreamCapability

fn clone(&self) -> StreamCapability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StreamCapability

impl Debug for StreamCapability

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

Formats the value using the given formatter.

impl Eq for StreamCapability

impl PartialEq for StreamCapability

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