Function escape_chars

pub fn escape_chars(input: &str, escape_braces: bool) -> String

Escapes special characters in a given input string.

This function replaces specific ASCII characters with their corresponding HTML entities. It is designed to handle both general HTML escaping and optional escaping of curly braces ({ and }).

Arguments

• input - The input string to escape.
• escape_braces - A boolean flag indicating whether to escape curly braces ({ and }).
  • If true, curly braces are escaped as { and }.
  • If false, curly braces are left unchanged.

Escaped Characters

The following characters are always escaped:

• & → &
• < → <
• > → >
• " → "
• ' → '
• / → /

If escape_braces is true, the following characters are also escaped:

• { → {
• } → }

Examples

Basic usage without escaping curly braces:

let input = r#"Hello, <world> & "friends"! {example}"#;
let escaped = escape_chars(input, false);
assert_eq!(escaped, r#"Hello, &lt;world&gt; &amp; &quot;friends&quot;! {example}"#);

Escaping curly braces:

let input = r#"Hello, <world> & "friends"! {example}"#;
let escaped = escape_chars(input, true);
assert_eq!(escaped, r#"Hello, &lt;world&gt; &amp; &quot;friends&quot;! &#123;example&#125;"#);
