Enum CrossOrigin 

pub enum CrossOrigin {
    Anonymous,
    UseCredentials,
}

The crossorigin attribute values for CORS requests.

Purpose

Controls how cross-origin requests are made for resources, determining whether credentials are sent and enabling CORS validation.

Usage Context

• Used with: <img>, <script>, <link>, <audio>, <video> elements
• Security: Required for accessing cross-origin resources with canvas/WebGL
• CORS: Server must send appropriate Access-Control headers

Valid Values

• Anonymous: CORS request without credentials
• UseCredentials: CORS request with credentials (cookies, certificates)

Example

use ironhtml_attributes::{AttributeValue, CrossOrigin};
let cors = CrossOrigin::Anonymous;
assert_eq!(cors.to_attr_value(), "anonymous");

<img src="https://cdn.example.com/image.jpg" crossorigin="anonymous">
<script src="https://cdn.example.com/lib.js" crossorigin="use-credentials"></script>
<link rel="stylesheet" href="https://cdn.example.com/style.css" crossorigin="anonymous">

Trait Implementations

impl AttributeValue for CrossOrigin

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

Convert to the attribute value string.

impl Clone for CrossOrigin

fn clone(&self) -> CrossOrigin

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrossOrigin

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

Formats the value using the given formatter.

impl PartialEq for CrossOrigin

fn eq(&self, other: &CrossOrigin) -> 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.
