Enum TextEffect 

pub enum TextEffect {
    Mutates,
    Preserves,
}

Whether an action can change buffer TEXT.

This exists so that anything cached against the buffer’s contents — today the search-match set, tomorrow anything else derived from it — is invalidated by construction rather than by remembering to. Search highlights were stale after every edit precisely because that invalidation was a thing to remember: SearchState::refresh existed and had zero callers, so inserting four characters repainted the highlight four columns off.

Variants

Mutates

May edit the active buffer. Derived state must be recomputed.

Preserves

Cannot edit the active buffer.
