Trait TableRow

This trait has to be implemented in order for [TableContent] to be able to render rows and the head row of the table. Usually this is done by #[derive(TableRow)].

Please see the simple example for how to use.

Required Associated Constants

const COLUMN_COUNT: usize

How many columns this row has (i.e. the number of fields in the struct)

Required Associated Types

type ClassesProvider: TableClassesProvider + Copy

Required Methods

fn render_row( row: RwSignal<Self>, index: usize, columns: RwSignal<Vec<Column>>, ) -> impl IntoView

Renders the inner of one row of the table using the cell renderers. This produces the children that go into the row_renderer given to [TableContent].

This render function has to render exactly one root element.

fn render_head_row<F>( sorting: Signal<VecDeque<(Column, ColumnSort)>>, on_head_click: F, drag_handlers: HeadDragHandler<Column>, columns: RwSignal<Vec<Column>>, ) -> impl IntoView

where F: Fn(TableHeadEvent<Column>) + Send + Clone + 'static,

Render the head row of the table.

fn columns() -> &'static [Column]

All columns this row can show in their default order.

fn col_name(col_index: Column) -> &'static str

The name of the column (= struct field name) at the given index. This can be used to implement sorting in a database. Information on column indexes is available at: the Column index type section.

Provided Methods

fn sorting_to_sql(sorting: &VecDeque<(Column, ColumnSort)>) -> Option<String>

where Column: Send + Sync + 'static,

Converts the given sorting to an SQL statement. Return None when there is nothing to be sorted otherwise Some("ORDER BY ..."). Uses Self::col_name to get the column names for sorting.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
