Struct OutputBuffer 

pub struct OutputBuffer { /* private fields */ }

Single ring buffer storing all output with source tags. Stdout/stderr views are filtered from the same data — no duplication.

Implementations

impl OutputBuffer

pub fn new(max_lines: usize) -> Self

pub fn push(&mut self, source: LineSource, line: String)

pub fn len(&self) -> usize

O(1) count of total lines.

pub fn is_empty(&self) -> bool

pub fn stdout_count(&self) -> usize

O(1) count of stdout lines.

pub fn stderr_count(&self) -> usize

O(1) count of stderr lines.

pub fn stdout_lines(&self) -> impl Iterator<Item = &str>

pub fn stderr_lines(&self) -> impl Iterator<Item = &str>

pub fn all_lines(&self) -> impl Iterator<Item = (LineSource, &str)>
