Struct ExtensionRegistry

pub struct ExtensionRegistry { /* private fields */ }

Available on crate feature plugins only.

Central registry for all ASS format extensions

Manages registration and lookup of tag handlers and section processors. Optimized for fast lookup during parsing with minimal memory overhead.

Implementations

impl ExtensionRegistry

pub fn new() -> Self

Create a new empty extension registry

pub fn register_tag_handler( &mut self, handler: Box<dyn TagHandler>, ) -> Result<()>

Register a new tag handler

Arguments

• handler - Boxed tag handler implementation

Errors

Returns PluginError::DuplicateHandler if handler name already exists

pub fn register_section_processor( &mut self, processor: Box<dyn SectionProcessor>, ) -> Result<()>

Register a new section processor

Arguments

• processor - Boxed section processor implementation

Errors

Returns PluginError::DuplicateHandler if processor name already exists

pub fn process_tag(&self, tag_name: &str, args: &str) -> Option<TagResult>

Process a tag using registered handlers

Arguments

• tag_name - Name of the tag to process
• args - Tag arguments as string slice

Returns

• Some(TagResult) - If a handler was found and executed
• None - If no handler was registered for this tag

pub fn process_section( &self, section_name: &str, header: &str, lines: &[&str], ) -> Option<SectionResult>

Process a section using registered processors

Arguments

• section_name - Name of the section to process
• header - Section header line
• lines - All lines in the section

Returns

• Some(SectionResult) - If a processor was found and executed
• None - If no processor was registered for this section

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

Get list of registered tag handler names

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

Get list of registered section processor names

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

Check if a tag handler is registered

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

Check if a section processor is registered

pub fn remove_tag_handler(&mut self, name: &str) -> Option<Box<dyn TagHandler>>

Remove a tag handler by name

Returns

• Some(handler) - If handler was found and removed
• None - If no handler with that name was registered

pub fn remove_section_processor( &mut self, name: &str, ) -> Option<Box<dyn SectionProcessor>>

Remove a section processor by name

Returns

• Some(processor) - If processor was found and removed
• None - If no processor with that name was registered

pub fn clear(&mut self)

Clear all registered handlers and processors

pub fn extension_count(&self) -> usize

Get total number of registered extensions
