Type Alias DrawAction

Type Declaration

• { mode: DrawState["mode"]; type: "start" }
• { type: "addVertex"; vertex: DrawVertex }
• { index: number; type: "updateVertex"; vertex: DrawVertex }
• { type: "undoVertex" }
• { type: "setHover"; vertex: DrawVertex | null }
• { dedupeEcho?: boolean; type: "finish" }

  dedupeEcho — drop a duplicate terminal vertex first (a dblclick-to-finish fires click+click, so ONLY the dblclick path passes true; Enter / auto-finish must not, or a deliberate re-click of the same spot — e.g. a facade base+top at one lng/lat — is eaten).

• { type: "cancel" }
• { type: "clear" }
