Enum InsertReason 

pub enum InsertReason {
    Enter(InsertEntry),
    Open {
        above: bool,
    },
    AfterChange,
    DeleteToEol,
    ReplayOnly,

    Replace,
}

Variants

Enter(InsertEntry)

Plain entry via i/I/a/A — recorded as InsertAt.

Open

Entry via o/O — records OpenLine on Esc.

Fields

above: bool

AfterChange

Entry via an operator’s change side-effect. Retro-fills the stored last-change’s inserted field on Esc.

DeleteToEol

Entry via C (delete to EOL + insert).

ReplayOnly

Entry via an insert triggered during dot-replay — don’t touch last_change because the outer replay will restore it.

BlockEdge

I or A from VisualBlock: insert the typed text at col on rows in top..=bot. col is the start column for I, the one-past-block-end column for A.

pad distinguishes the two vim behaviours at rows shorter than col (:h v_b_I vs :h v_b_A): A pads short rows with spaces so the appended text still lines up (pad: true); I skips rows that don’t reach col entirely — no padding, no insert on that row (pad: false).

Fields

top: usize

bot: usize

col: usize

pad: bool

BlockChange

c from VisualBlock: block content deleted, then user types replacement text replicated across all block rows on Esc. Cursor advances to the last typed char after replication (unlike BlockEdge which leaves cursor at the insertion column).

Fields

top: usize

bot: usize

col: usize

Replace

R — Replace mode. Each typed char overwrites the cell under the cursor instead of inserting; at end-of-line the session falls through to insert (same as vim).
