Struct ListTab 

pub struct ListTab<M> { /* private fields */ }

One tab a table offers above its rows: a preset predicate the reader picks with ?tab=<key>, beside the search and the filters it combines with.

The first tab is the one a list without ?tab= shows, so a list whose first tab narrows its rows opens on that tab. A ?tab= naming no tab the table declares is never dropped silently: the list shows its warning banner, and the export and a selection of every matching record refuse it, as they do an unknown filter.

A tab narrows what the list shows; it is not access control. A tab whose query reads a field field_access hides from the user does not show to them: the panel reads the fields off the query.

use tablo_core::{ListTab, Table, TextColumn, lens};

Table::new(TextColumn::new(lens!(Post.title)))
    .tab(ListTab::new("all", "All"))
    .tab(
        ListTab::new("drafts", "Drafts")
            .query(Post::fields().published().eq(false))
            .badge(),
    );

Implementations

impl<M> ListTab<M>

pub fn new(key: impl Into<String>, label: impl Into<Text>) -> Self

A tab admitting every row, whose ?tab= value is key and whose link reads label.

pub fn query(self, predicate: Expr<bool>) -> Self

Admit only the rows predicate selects.

pub fn badge(self) -> Self

Show how many rows the tab holds under the list’s search and filters: one count query per badged tab, each time the list renders.

Trait Implementations

impl<M> Clone for ListTab<M>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
