Enum NodeKind 

pub enum NodeKind {
    Source,
    Filter,
    Sink,
    Mux,
}

Classification of a graph node by its role in the pipeline.

Variants

Source

Produces frames (decoder, file reader, live capture).

Filter

Transforms frames (scaler, colour converter, denoiser).

Sink

Consumes frames (encoder, display, file writer).

Mux

Splits or merges multiple streams.

Implementations

impl NodeKind

pub fn is_source(&self) -> bool

Returns true if this node kind originates data in the graph.

pub fn is_sink(&self) -> bool

Returns true if this node kind terminates a pipeline branch.

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

Returns a short human-readable label for the kind.

Trait Implementations

impl Clone for NodeKind

fn clone(&self) -> NodeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeKind

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

Formats the value using the given formatter.

impl Eq for NodeKind

impl Hash for NodeKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeKind

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