Struct CapturedOutput 

pub struct CapturedOutput { /* private fields */ }

Bounded, incrementally-appended output capture shared (via Arc) between a job’s stdout/stderr reader tasks and whatever later polls it (background_status/background_list). Thread-safe; every method is fail-soft on a poisoned lock (treats it as “temporarily unavailable”, the same posture crate::permissions::approval::ApprovalCache already documents for itself) rather than panicking a reader task or a tool call.

Implementations

impl CapturedOutput

pub fn new() -> CapturedOutput

A fresh, empty capture.

pub fn append(&self, chunk: &str, cap: usize)

Append chunk, never growing the retained buffer past cap bytes — bytes beyond the cap are DROPPED (fail-closed, never buffered) and truncated latches true the first time that happens and stays true thereafter. A caller must keep reading the underlying pipe past this point regardless (to avoid blocking the child on a full, undrained pipe) — this method only bounds what’s RETAINED in memory, not what’s read off the pipe.

pub fn snapshot(&self) -> (String, bool)

The full captured text so far, and whether it was ever truncated.

pub fn drain_new(&self) -> String

Text appended since the last drain_new call (or since creation, on the first call) — the event-feed’s per-poll delta. Advances the drain cursor even on an empty result, so polling twice in a row with no new output between them returns "" the second time, never a repeat of the first drain.
