Struct CaptureChannel 

pub struct CaptureChannel { /* private fields */ }

Test-capture impl: records every op-output line for assertions and writes no fd. The SRD-87 §12 surface-agreement / no-bypass tests install one of these and inspect Self::op_lines.

Implementations

impl CaptureChannel

pub fn new() -> Self

pub fn op_lines(&self) -> Vec<String>

Every op-output line submitted so far, in submission order.

pub fn log_lines(&self) -> Vec<(LogLevel, String)>

Every log-bucket line submitted so far, in submission order.

pub fn raster_frames(&self) -> Vec<String>

Every raster-bucket frame submitted so far, in submission order.

Trait Implementations

impl Clone for CaptureChannel

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for CaptureChannel

fn default() -> Self

Returns the “default value” for a type.

impl OutputChannel for CaptureChannel

fn op_output(&self, line: &str)

op-output bucket: one adapter-rendered op line. Reaches the terminal/file the channel owns — never around it.

fn log(&self, level: LogLevel, message: &str)

log bucket: project one diagnostic line to the live terminal (SRD-87 §5). This is the output half only — the durable session.log write and the fold-ring append are L1 intake, done by observer::log_categorized before this is ever called, and the sink_active/min_level gate (whether a line reaches the live surface at all) stays with the observer. The default writes the colorized line to stderr — the fd the channel owns. A sink-active interactive run never reaches here (the sink renders from the ring); a console-owning run never reaches here (suppressed upstream); piped and bootstrap runs land here.

fn raster(&self, frame: &str)

raster bucket: a fully-rendered, self-contained terminal frame (braille / ANSI cells) — e.g. the plotter’s canvas (SRD-87 §5). The producer owns layout (cursor controls, line endings); the channel owns the fd. The default writes the frame bytes raw to the stdout the channel owns — correct for a console-owning adapter (the plotter owns the screen) and for a piped plot redirected to a file.
