htmlentity

A library for encoding and decoding HTML entities.

How to use

use htmlentity::entity::{ encode, decode, EncodeType, CharacterSet, ICodedDataTrait };
use htmlentity::types::{ AnyhowResult, Byte };
fn main() -> AnyhowResult<()> {
  let html = "<div name='htmlentity'>Hello!世界!</div>";
  let html_after_encoded = "&lt;div name='htmlentity'&gt;Hello!&#x4e16;&#x754c;!&lt;/div&gt;";
  // encode
  let encoded_data = encode(
    html.as_bytes(), 
    // encode format
    &EncodeType::NamedOrHex,
    // charcters need to be encoded 
    &CharacterSet::HtmlAndNonASCII
  );
  assert_eq!(encoded_data.to_bytes(), html_after_encoded.as_bytes());
  assert_eq!(encoded_data.to_string()?, String::from(html_after_encoded));
  let char_list = String::from(html_after_encoded).chars().collect::<Vec<char>>();
  assert_eq!(encoded_data.to_chars()?, char_list);
  // decode
  let bytes = encoded_data.into_iter().map(|(byte, _)| *byte).collect::<Vec<Byte>>();
  let decoded_data = decode(&bytes);
  assert_eq!(decoded_data.to_bytes(), html.as_bytes());
  assert_eq!(decoded_data.to_string()?, String::from(html));
  let char_list = String::from(html).chars().collect::<Vec<char>>();
  assert_eq!(decoded_data.to_chars()?, char_list);
  // shortcut usage
  assert_eq!(
    encode(
      html.as_bytes(), 
      &EncodeType::NamedOrHex,
      &CharacterSet::HtmlAndNonASCII,
    ).to_string()?,
    String::from(html)
  );
  Ok(())
}
