Struct Graph 

pub struct Graph { /* private fields */ }

Immutable graph ready for validation and future rendering.

Implementations

impl Graph

pub const fn identity(&self) -> GraphIdentity

Returns the graph node-content identity shared by clones of the same built graph.

pub fn with_source_media( self, node_id: NodeId, media: ClipMedia, ) -> Result<Graph, PixelFlowError>

Returns graph clone with one source node media description replaced.

pub fn with_source_capabilities( self, node_id: NodeId, capabilities: SourceCapabilities, ) -> Result<Graph, PixelFlowError>

Returns graph clone with one source node scheduling capabilities replaced.

pub fn with_replanned_filter_media( self, registry: &FilterRegistry, metadata_schema: &MetadataSchema, ) -> Result<Graph, PixelFlowError>

Returns graph with reachable filter plans refreshed from current input media.

pub fn node(&self, id: NodeId) -> Option<&GraphNode>

Returns node by ID.

pub fn nodes(&self) -> &[GraphNode]

Returns all stored nodes.

pub fn outputs(&self) -> &[Clip]

Returns final output clips declared by graph construction.

pub fn with_single_output(self, output: Clip) -> Result<Graph, PixelFlowError>

Returns a graph clone with exactly one final output clip.

pub fn validation_plan(&self) -> Result<ValidationPlan, PixelFlowError>

Finds reachable nodes and sources from single final output.

pub fn validate(&self) -> Result<ValidatedGraph, PixelFlowError>

Validates topology and media constraints for reachable output graph.

Trait Implementations

impl Clone for Graph

fn clone(&self) -> Graph

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Graph

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

Formats the value using the given formatter.

impl PartialEq for Graph

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