Enum CellKind 

pub enum CellKind {
    Text,
    Numeric {
        step: f64,
    },
    Choice {
        options: Vec<String>,
    },
    Button {
        label: String,
    },
    Actions {
        label: String,
    },
    Badges,
    Toggle,
    ReadOnly,
}

What a column’s cells are, and therefore which editor the widget draws.

Variants

Text

Free text. Committed on focus-loss / Enter, NOT per keystroke.

Numeric

A number, edited with a drag-value.

Fields

step: f64

Choice

A fixed set of choices — a combobox. An empty string is always offered as the “unset” choice, so a user can clear a cell.

Fields

options: Vec<String>

Button

An action button in every row of the column. The widget reports the click (ColumnTreeOut::buttons); the consumer acts.

Fields

label: String

Actions

The row’s ACTION MENU trigger. Every row draws label; clicking it opens that row’s RowNode::actions — the same menu a right-click on the row opens. A row that declares no action draws the trigger greyed.

Fields

label: String

Badges

Status glyphs drawn inline, from a cell value shaped [{"glyph": "⏚", "color": "#ff9f0a", "tooltip": "…"}, …] (color and tooltip optional). An optional action makes a glyph a button that emits a row action. A plain text cell cannot colour part of its own content, and these glyphs carry meaning IN their colour — a constraint status, an out-of-date badge — so they get a kind rather than being flattened into a string.

Toggle

A boolean, drawn as a checkbox. The cell’s value is read with Value::as_bool; a missing value reads false. A row that is not RowNode::editable still DRAWS its box (so the column stays readable) but cannot be clicked — a derived grouping row has no state of its own to toggle.

ReadOnly

Displayed, never edited (a derived value — a rolled-up quantity, a computed length).
