Struct FilterRegistry 

pub struct FilterRegistry { /* private fields */ }

Per-core registry for filters and metadata extension keys.

Implementations

impl FilterRegistry

pub fn new() -> FilterRegistry

Creates an empty registry with core metadata keys installed.

pub fn register_filter( &mut self, descriptor: FilterDescriptor, ) -> Result<(), PixelFlowError>

Registers one filter descriptor.

pub fn register_filter_planner( &mut self, descriptor: FilterDescriptor, planner: fn(FilterPlanRequest<'_>) -> Result<FilterPlan, PixelFlowError>, ) -> Result<(), PixelFlowError>

Registers one filter descriptor with graph-construction planner.

pub fn register_filter_expander( &mut self, descriptor: FilterDescriptor, expander: RegisteredFilterExpander, ) -> Result<(), PixelFlowError>

Registers one filter descriptor with graph-construction expansion.

pub fn register_filter_runtime( &mut self, descriptor: FilterDescriptor, planner: Option<RegisteredFilterPlanner>, expander: Option<RegisteredFilterExpander>, executor_factory: Option<RegisteredExecutorFactory>, ) -> Result<(), PixelFlowError>

Registers one filter descriptor with plugin-provided runtime callbacks.

pub fn plan_filter( &self, name: &str, input_media: &[ClipMedia], options: &BTreeMap<String, FilterOptionValue>, ) -> Result<FilterPlan, PixelFlowError>

Plans one registered filter call.

pub fn plan_public_filter( &self, name: &str, input_media: &[ClipMedia], options: &BTreeMap<String, FilterOptionValue>, ) -> Result<FilterPlan, PixelFlowError>

Plans one public script-visible filter call.

pub fn expand_public_filter( &self, name: &str, builder: &mut GraphBuilder, input_clips: &[Clip], input_media: &[ClipMedia], options: &BTreeMap<String, FilterOptionValue>, metadata_schema: &MetadataSchema, ) -> Result<Option<FilterExpansionOutput>, PixelFlowError>

Expands one public script-visible filter call, if it has an expander.

pub fn create_filter_executor( &self, name: &str, input_media: &[ClipMedia], output_media: &ClipMedia, options: &BTreeMap<String, FilterOptionValue>, metadata_schema: &MetadataSchema, ) -> Option<Result<Arc<dyn FrameExecutor>, PixelFlowError>>

Creates a runtime executor for a registered filter, if it provides a factory.

pub fn build_registered_filter_executors( &self, graph: &Graph, metadata_schema: &MetadataSchema, executors: &mut RenderExecutorMap, ) -> Result<(), PixelFlowError>

Adds runtime executors for reachable filter nodes backed by this registry.

pub fn resolve_filter_name_for_plugin_call( &self, plugin_namespace: &str, filter_name: &str, ) -> Result<&str, PixelFlowError>

Resolves plugin.<namespace>.<filter> script sugar to a registered filter name.

pub fn register_metadata_key( &mut self, key: &str, kind: MetadataKind, ) -> Result<(), PixelFlowError>

Registers one plugin metadata key.

pub fn filter_descriptor(&self, name: &str) -> Option<&FilterDescriptor>

Returns descriptor for registered filter.

pub fn contains_filter(&self, name: &str) -> bool

Returns true when filter exists.

pub fn contains_public_filter(&self, name: &str) -> bool

Returns true when filter exists and is public.

pub fn filter_names(&self) -> Vec<&str>

Returns filter names in deterministic order.

pub fn public_filter_names(&self) -> Vec<&str>

Returns public filter names in deterministic order.

pub const fn metadata_schema(&self) -> &MetadataSchema

Returns metadata schema including plugin extension keys.
