Enum Enctype 

pub enum Enctype {
    UrlEncoded,
    Multipart,
    Plain,
}

The enctype attribute values for form encoding.

Purpose

Specifies how form data should be encoded before sending to the server, which is critical for proper handling of different types of form content.

Usage Context

• Used with: <form> elements (and <input>/<button> with formenctype)
• Only relevant: When method="post"
• Default: application/x-www-form-urlencoded

Valid Values

• UrlEncoded: Standard URL-encoded format (default)
• Multipart: Multipart form data (required for file uploads)
• Plain: Plain text format (rarely used, debugging only)

Example

use ironhtml_attributes::{AttributeValue, Enctype};
let enctype = Enctype::Multipart;
assert_eq!(enctype.to_attr_value(), "multipart/form-data");

<form action="/submit" method="post" enctype="application/x-www-form-urlencoded">...</form>
<form action="/upload" method="post" enctype="multipart/form-data">
  <input type="file" name="document">
</form>
<form action="/feedback" method="post" enctype="text/plain">...</form>

Trait Implementations

impl AttributeValue for Enctype

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

Convert to the attribute value string.

impl Clone for Enctype

fn clone(&self) -> Enctype

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Enctype

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

Formats the value using the given formatter.

impl PartialEq for Enctype

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