Function find_all 

pub fn find_all(
    buffer: &Buffer,
    regex: &Regex,
    cancel: &CancellationToken,
) -> CoreResult<Vec<Range>>

Find every occurrence of the regex in the buffer. Returns the positional ranges in left-to-right order. Empty for matchless patterns and patterns whose minimum length exceeds the buffer.

Walks the rope’s chunk iterator – never allocates the whole buffer text. Per-call cost on literal patterns is dominated by the SIMD prefilter via the regex crate’s literal extraction.

cancel is polled between matches and at chunk boundaries inside the inner walks. A flipped token short-circuits with CoreError::Cancelled; partial results are discarded.

Matches never overlap: scanning resumes at the end of each match (one UTF-8 scalar further for a zero-width match).

Examples

use fancy_regex::Regex;
use lattice_core::Buffer;
use lattice_core::protocol::CancellationToken;
use lattice_core::protocol::position::{Position, Range};
use lattice_core::search::find_all;

let buf = Buffer::from_text("foo bar\nbaz foo\n");
let re = Regex::new("fo+")?;
let hits = find_all(&buf, &re, &CancellationToken::never())?;
assert_eq!(
    hits,
    [
        Range::new(Position::new(0, 0), Position::new(0, 3)),
        Range::new(Position::new(1, 4), Position::new(1, 7)),
    ],
);
