Enum Scope 

pub enum Scope {
    Row,
    Col,
    Rowgroup,
    Colgroup,
}

The scope attribute values for table header cells.

Purpose

Specifies which cells a header (<th>) element applies to, improving table accessibility by defining the relationship between headers and data.

Usage Context

• Used with: <th> elements only
• Accessibility: Critical for screen readers to understand table structure
• Required: For complex tables with multiple header levels

Valid Values

• Row: Header applies to all cells in the same row
• Col: Header applies to all cells in the same column
• Rowgroup: Header applies to row group (<tbody>, <thead>, <tfoot>)
• Colgroup: Header applies to column group (<colgroup>)

Example

use ironhtml_attributes::{AttributeValue, Scope};
let scope = Scope::Col;
assert_eq!(scope.to_attr_value(), "col");

<table>
  <thead>
    <tr>
      <th scope="col">Name</th>
      <th scope="col">Age</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">John</th>
      <td>30</td>
    </tr>
  </tbody>
</table>

Trait Implementations

impl AttributeValue for Scope

fn to_attr_value(&self) -> Cow<'static, str>

Convert to the attribute value string.

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scope

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

Formats the value using the given formatter.

impl PartialEq for Scope

fn eq(&self, other: &Scope) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Scope

impl Eq for Scope

impl StructuralPartialEq for Scope
