Fields

count: usize

row_min: usize

Min/max row visited during this session. Widens on every key.

row_max: usize

before_rope: Rope

O(1) rope snapshot of the full buffer at session entry. Used to diff the affected row window at finish without being fooled by cursor navigation through rows the user never edited. ropey::Rope::clone is Arc-clone — no byte copying.

reason: InsertReason

start_row: usize

(row, col) where the insert session began (char-indexed). Abbreviation expansion uses start_col as mincol — only chars at or after this column on start_row are eligible as part of the lhs match, so pre-existing buffer text is never consumed by expansion.

start_col: usize

backspaces: usize

<BS> / <C-h> presses that deleted at or before the insert’s start (vim’s Insstart). Each one moves start_row / start_col back to where it left the cursor, as vim moves Insstart, and . replays them before retyping, as vim’s redo buffer does.

deleted: isize

Characters those backspaces removed, net of any spaces a 'softtabstop' delete put back — what the typed text’s length is measured against when the session ends.

wraps: Vec<InsertWrap>

The line breaks 'formatoptions' t put in while typing, oldest first. vim’s redo holds the typed keys, not the breaks, so the session takes them back out when it reads what was typed.
