Struct Segment 

pub struct Segment {
    pub start: usize,
    pub end: usize,
    pub byte_start: usize,
    pub byte_end: usize,
    pub slots_before: usize,
}

One line’s char range [start, end) into the content, with the matching byte range and the count of island slots before the line — so a caller indexes the content text and the island list in O(1) without rescanning.

Fields

start: usize

USV index of the line’s first char.

end: usize

USV index one past the line’s last char (its \n, or the content end).

byte_start: usize

Byte offset of start in the content text.

byte_end: usize

Byte offset of end in the content text.

slots_before: usize

Count of ISLAND_SLOT chars before start.
