Struct GraphBuilder 

pub struct GraphBuilder { /* private fields */ }

Mutable construction API. build freezes nodes into immutable graph.

Implementations

impl GraphBuilder

pub const fn new() -> Self

Creates empty graph builder.

pub fn source(&mut self, name: impl Into<String>, media: ClipMedia) -> Clip

Adds source node and returns immutable clip handle.

pub fn source_with_request( &mut self, request: SourceRequest, media: ClipMedia, ) -> Clip

Adds source node with explicit request metadata.

pub fn source_with_capabilities( &mut self, name: impl Into<String>, media: ClipMedia, capabilities: SourceCapabilities, ) -> Clip

Adds source node with explicit scheduler capabilities.

pub fn source_with_request_and_capabilities( &mut self, request: SourceRequest, media: ClipMedia, capabilities: SourceCapabilities, ) -> Clip

Adds source node with explicit request metadata and scheduler capabilities.

pub fn filter( &mut self, name: impl Into<String>, inputs: &[Clip], media: ClipMedia, compatibility: FilterCompatibility, ) -> Result<Clip>

Adds filter node and returns new immutable clip handle.

pub fn filter_with_schedule( &mut self, name: impl Into<String>, inputs: &[Clip], media: ClipMedia, compatibility: FilterCompatibility, dependencies: DependencyPattern, concurrency: ConcurrencyClass, ) -> Result<Clip>

Adds filter node with explicit scheduling contract.

pub fn filter_with_schedule_and_options( &mut self, name: impl Into<String>, inputs: &[Clip], media: ClipMedia, compatibility: FilterCompatibility, dependencies: DependencyPattern, concurrency: ConcurrencyClass, options: FilterOptions, ) -> Result<Clip>

Adds filter node with explicit scheduling contract and stored options.

pub fn set_output(&mut self, output: Clip)

Replaces final output list with one clip.

pub fn add_output(&mut self, output: Clip)

Adds final output clip. Phase 1 validation rejects multiple outputs.

pub fn build(self) -> Graph

Freezes builder into immutable graph.

Trait Implementations

impl Clone for GraphBuilder

fn clone(&self) -> GraphBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphBuilder

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

Formats the value using the given formatter.

impl Default for GraphBuilder

fn default() -> GraphBuilder

Returns the “default value” for a type.

impl PartialEq for GraphBuilder

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