Struct Segment 

pub struct Segment {
    pub file_idx: u32,
    pub scan_start: u32,
    pub emit_start: u32,
    pub emit_end: u32,
}

One scan window of a file.

All offsets are file-relative bytes. Invariant: scan_start <= emit_start < emit_end and scan_start == emit_start - overlap clamped at 0.

Fields

file_idx: u32

Index into the file table this window belongs to.

scan_start: u32

File-relative offset where scanning begins (DFA-state warm-up start).

emit_start: u32

First file-relative offset this window OWNS: a match whose end offset is in [emit_start, emit_end) is emitted here; an end < emit_start belongs to the previous window’s owned region.

emit_end: u32

Exclusive end of both the owned (emit) range and the scan range.

Implementations

impl Segment

pub const fn scan_len(&self) -> u32

Total bytes this window scans (warm-up prefix + owned region).

pub const fn emit_len(&self) -> u32

Bytes this window owns (emits matches for).

pub const fn abi_words(&self) -> [u32; 4]

The device-ABI words for this segment, in the exact order the kernel decodes them from segments[seg_idx * SEGMENT_WORDS ..]: [file_idx, scan_start, emit_start, emit_end] (offsets file-relative the kernel adds file_offsets[file_idx] to reach the packed haystack).
