Struct StderrSink 

pub struct StderrSink;

Default sink. Writes linesmith [<tag>]: <msg> lines to io::stderr().lock() and drops the write on a closed pipe / full disk: the statusline has no recovery path, and panicking here would nuke an otherwise-good render.

Trait Implementations

impl Debug for StderrSink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StderrSink

fn default() -> StderrSink

Returns the “default value” for a type.

impl LogSink for StderrSink

fn emit(&self, lvl: Level, msg: &str)

Emit a level-gated diagnostic. The caller has already confirmed the level is enabled — the sink writes unconditionally. Implementations defensively no-op on Level::Off rather than relying on the caller; the macros never pass Off, but emit() is pub.

fn emit_error(&self, msg: &str)

Emit a structural-failure diagnostic. Always fires regardless of the configured level — LINESMITH_LOG=off users still see “the statusline broke” because there’s no other channel.
