Implementations

impl PluginRegistry

pub const fn new() -> PluginRegistry

Creates an empty registry.

pub fn register_plugin<P>(&mut self, plugin: &P)

where P: QrPlugin + ?Sized,

Registers all extension points provided by plugin.

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

Returns the registered version for a plugin name.

pub fn plugin_names(&self) -> impl Iterator<Item = &str>

Iterates registered plugin names in deterministic order.

pub fn register_renderer( &mut self, name: impl Into<String>, factory: Box<dyn RendererFactory>, ) -> Option<Box<dyn RendererFactory>>

Registers or replaces a renderer factory by name.

pub fn register_encoder( &mut self, name: impl Into<String>, factory: Box<dyn EncoderFactory>, ) -> Option<Box<dyn EncoderFactory>>

Registers or replaces an encoder factory by name.

pub fn register_postprocessor(&mut self, postprocessor: Box<dyn PostProcessor>)

Appends a postprocessor to the registry.

pub fn renderer(&self, name: &str) -> Option<&dyn RendererFactory>

Returns a renderer factory by name.

pub fn build_renderer( &self, name: &str, config: &RenderConfig, ) -> Result<Box<dyn DynRenderer>, PluginError>

Builds a renderer by name.

Errors

Returns PluginError::RendererNotFound when no renderer factory is registered with name.

pub fn encoder(&self, name: &str) -> Option<&dyn EncoderFactory>

Returns an encoder factory by name.

pub fn build_encoder( &self, name: &str, config: &EncodeConfig, ) -> Result<Box<dyn DynEncoder>, PluginError>

Builds an encoder by name.

Errors

Returns PluginError::EncoderNotFound when no encoder factory is registered with name.

pub fn postprocessors(&self) -> &[Box<dyn PostProcessor>]

Returns all postprocessors in registration order.

pub fn process_modules( &self, modules: &mut dyn ModuleStorage, ) -> Result<(), PluginError>

Applies all registered postprocessors in registration order.

Errors

Returns the first PluginError reported by a postprocessor.

pub fn renderer_names(&self) -> impl Iterator<Item = &str>

Iterates renderer names in deterministic order.

pub fn encoder_names(&self) -> impl Iterator<Item = &str>

Iterates encoder names in deterministic order.
