pub fn emit_stream_trailer<T: Serialize>(value: &T) -> Result<(), AppError>Expand description
Writes the line that ends a stream, carrying its one agent_surface record.
GAP-SG-215. Never shaped: the trailer describes the stream, so a --select
aimed at the records must neither fail on it nor rewrite it. Both were
measured — --select name export exited 2 on this line, and
--select namespace export silently deleted summary: true from it.
§Errors
Returns Err when serialization fails or on a non-BrokenPipe I/O error.
