Struct InspectLineSink 

pub struct InspectLineSink<F> { /* private fields */ }

LineSink wrapping a per-line closure. Compose with LineAdapter to drive inspect_lines, or to build your own custom inspect-lines consumer outside the built-in factory methods.

Implementations

impl<F> InspectLineSink<F>

where F: FnMut(Cow<'_, str>) -> Next + Send + 'static,

pub fn new(f: F) -> Self

Creates a new sink that calls f once for each parsed line.

Trait Implementations

impl<F> LineSink for InspectLineSink<F>

where F: FnMut(Cow<'_, str>) -> Next + Send + 'static,

type Output = ()

Final value produced once the adapter is finished. Returned via Consumer::wait.

fn on_line(&mut self, line: Cow<'_, str>) -> Next

Invoked for every parsed line. Return Next::Break to stop further parsing.

fn into_output(self) -> Self::Output

Consumes the sink and returns its final output.

fn on_gap(&mut self)

Invoked after the adapter resets the parser following a stream gap. The default does nothing; override when the inner sink keeps line-spanning state that the gap invalidates.

fn on_eof(&mut self)

Invoked once the adapter finishes flushing any trailing line at EOF. The default does nothing; override for sinks that want a finalization hook beyond the last on_line call.
