Struct RichTextColumn 

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

A column of a String field holding a rich text field’s HTML. A detail page shows the formatted HTML; a table cell shows its text, cut to excerpt characters; an export holds the text.

tablo_core::RichTextColumn::new(tablo_core::lens!(Post.body));

The HTML is cleaned again as it renders, keeping what any Tool produces, since a seed, a migration or another app can write the column without the field’s cleaning.

Implementations

impl<M, T> RichTextColumn<M, T>

where M: Model,

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

where T: Field<Inner = String>,

Bind the column to the String or Option<String> field lens reads.

pub fn excerpt(self, chars: usize) -> Self

The most characters of text a table cell shows, followed by … when the text runs on; 120 by default.

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 RichTextColumn<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 RichTextColumn<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 RichTextColumn<M, T>

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

Formats the value using the given formatter.
