Struct DiskLogReader 

pub struct DiskLogReader { /* private fields */ }

Provides random-access line reading from disk log files using the sidecar .idx index. Handles rotated files (.1, .2, …) transparently.

Implementations

impl DiskLogReader

pub fn new(log_dir: PathBuf, process: String) -> Self

pub fn line_count(&mut self, source: LineSource) -> usize

Total line count for a stream across current + rotated files.

pub fn line_count_both(&mut self) -> usize

Total line count for merged both-streams view.

pub fn read_lines( &mut self, source: LineSource, start: usize, count: usize, ) -> Result<Vec<String>>

Read lines [start..start+count) for a single stream, spanning rotated files oldest-to-newest.

pub fn read_interleaved( &mut self, start: usize, count: usize, ) -> Result<Vec<(LineSource, String)>>

Read interleaved lines for “Both” mode, merge-sorted by sequence number.

pub fn scan_matching_lines( &mut self, filter: &str, mode: StreamMode, ) -> Vec<usize>

Scan all lines in the given stream mode and return indices of lines matching the filter substring. The returned indices are positions within the mode’s address space (single-stream or interleaved).

pub fn scan_matching_lines_from( &mut self, filter: &str, mode: StreamMode, start_from: usize, ) -> Vec<usize>

Scan lines starting from start_from in the given stream mode. Returns indices of matching lines and can be used for incremental updates.

pub fn read_scattered_lines( &mut self, mode: StreamMode, line_numbers: &[usize], ) -> Vec<(LineSource, String)>

Read specific non-contiguous lines by index within the given mode’s address space. Used by filtered scrollback to render only matching lines.
