Struct ListColumn 

pub struct ListColumn<M, T> { /* private fields */ }

A column of a Vec of FormScalar values that one list column stores, such as a multiple choice’s.

A table cell and a detail page show a badge per value, in the stored order: its FormScalar::to_label, an Options enum’s label with its color or icon, or any other type’s form spelling. An empty list shows the dash an empty text does. The text, as an export writes it, joins the labels with , .

tablo_core::ListColumn::new(tablo_core::lens!(Post.keywords));

Implementations

impl<M, T> ListColumn<M, T>

where M: Model, T: FormScalar,

pub fn new(lens: Lens<M, Vec<T>, List<T>>) -> Self

Bind the column to the list lens reads.

pub fn label(self, label: impl Into<Text>) -> Self

Replace the label the field’s name gives it.

pub fn width(self, width: ColumnWidth) -> Self

Declare this column’s width.

pub fn toggleable(self) -> Self

Let each reader hide this column from their list; it starts shown.

pub fn hidden_by_default(self) -> Self

Let each reader show this column in their list; it starts hidden.

Trait Implementations

impl<M, T> Clone for ListColumn<M, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<M, T> Column<M> for ListColumn<M, T>

where M: Model + Send + Sync + 'static, T: FormScalar + Send + Sync + 'static,

fn name(&self) -> &str

The column’s identifier, distinct within its table.

fn label(&self) -> Text

The header text.

fn column_width(&self) -> ColumnWidth

The width the column claims.

fn toggle(&self) -> ColumnToggle

Whether each reader may hide or show the column in their list, and how it starts. A detail page shows every column.

fn reads(&self) -> Option<Reads<M>>

The fields of the row text, cell, entry, search_expr and order_by read, or None when the column does not say.

fn text(&self, cx: &Cx, row: &M) -> String

The row’s value as plain text.

fn cell<'a>(&self, cx: &'a Cx, row: &M) -> BoxView<'a>

The row’s table cell.

fn entry<'a>(&self, cx: &'a Cx, row: &M) -> BoxView<'a>

The record’s entry on a detail page: the label over the cell.

fn alignment(&self) -> Alignment

Where the header and the cells align their content.

fn search_expr(&self, _term: &str) -> Option<Expr<bool>>

The predicate a search for term adds, or None when the column does not join the table’s search. A column that joins it answers Some for every non-empty, trimmed term.

fn order_by(&self, _descending: bool) -> Option<OrderByExpr>

The ordering a sort on this column applies, or None when the header does not link to a sort on it. A sortable column answers Some either way.

fn includes(&self) -> Includes<M>

The relations text, cell and entry read.

impl<M, T> Debug for ListColumn<M, T>

fn fmt(&self, __f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<M, T> IntoDetail<M> for ListColumn<M, T>

where Self: Column<M> + 'static,

fn into_detail(self) -> Detail<M>
