Struct CommandTranscript 

pub struct CommandTranscript<'context> { /* private fields */ }

Publishes a contained command’s output lines onto an activity’s transcript.

Built for one command execution and passed to run_cancellable_command as its observer. On a context with no live transcript seam — every isolated unit test, and any activity whose host installed none — emitting is the documented no-op that ActivityContext::emit_event already is, so a command runs exactly as it did before.

Implementations

impl<'context> CommandTranscript<'context>

pub fn new(context: &'context ActivityContext) -> Self

Build a transcript publisher for the command context is executing.

pub fn for_body_line( context: &'context ActivityContext, position: usize, total: usize, ) -> Self

Build a transcript publisher for ONE line of a declared command’s body, whose events say which line they came from: command stdout (line 2 of 5).

position is one-based, counted the way the body’s failures count it, so a reader comparing a failure sentence against the transcript is comparing the same numbers.
