Struct CircularBuffer 

pub struct CircularBuffer { /* private fields */ }

Circular buffer for storing PTY output lines with configurable size limit Provides efficient memory-bounded storage with O(1) append operations

Implementations

impl CircularBuffer

pub fn new(max_size: usize) -> Self

Create a new circular buffer with the specified maximum size

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

Add a line to the buffer, removing the oldest if at capacity

pub fn len(&self) -> usize

Get the current number of lines in the buffer

pub fn is_empty(&self) -> bool

Check if the buffer is empty

pub fn get_all_lines(&self) -> Vec<String>

Get all lines as a vector (for display purposes)

pub fn get_last_lines(&self, n: usize) -> Vec<String>

Get the last N lines (most recent)

pub fn get_lines_range(&self, start: usize, count: usize) -> Vec<String>

Get lines within a range (for scrolling)

pub fn get_content(&self) -> String

Get all lines as a single string (joined with newlines)

pub fn get_recent_content(&self, lines: usize) -> String

Get the last N lines as a single string

pub fn clear(&mut self)

Clear the buffer

pub fn max_size(&self) -> usize

Get maximum buffer size

pub fn set_max_size(&mut self, new_max_size: usize)

Set new maximum size (may truncate existing content)

pub fn get_stats(&self) -> BufferStats

Get diagnostic information about the buffer

pub fn search(&self, query: &str) -> Vec<(usize, String)>

Search for lines containing the given text (case-insensitive)

pub fn get_lines_reverse(&self) -> Vec<String>

Get lines in reverse order (most recent first)
