Plugin trait for custom content processors.

Plugins intercept input lines and can:

• Transform them into different output
• Buffer multiple lines before emitting
• Pass through to normal processing

Required Methods

fn name(&self) -> &str

Plugin name for identification and logging.

fn process_line( &mut self, line: &str, state: &ParseState, style: &ComputedStyle, ) -> Option<ProcessResult>

Process a line of input.

Returns

• None: Plugin not interested, continue normal processing
• Some(ProcessResult::Lines(vec)): Emit these lines instead
• Some(ProcessResult::Continue): Plugin consumed input, keep buffering

fn flush(&mut self) -> Option<Vec<String>>

Called when stream ends to flush any buffered content.

Returns

• None: Nothing to flush
• Some(vec): Remaining buffered lines to emit

fn reset(&mut self)

Reset plugin state.

Called when starting a new document or clearing state.

Provided Methods

fn priority(&self) -> i32

Plugin priority (lower = higher priority).

Default is 0. Plugins with lower priority numbers are called first.

fn is_active(&self) -> bool

Whether this plugin is currently active (buffering).

Active plugins get priority for subsequent lines.
