do_html!($html, $key, and $val)

Macro Rules

The do_html macro takes an HTML string along with key-value pairs and replaces placeholders in the HTML (formatted as {{key}}) with the corresponding values. It returns the processed HTML string with the substitutions applied.

Parameters

• $html: The HTML string containing placeholders for substitution (e.g., "<p>Hello, {{name}}!</p>").
• $key: The identifier for each placeholder in the HTML (e.g., name).
• $val: The value that replaces the corresponding placeholder in the HTML (e.g., "Alice").

Examples

// use cans::html::do_html;
use cans::do_html;

let template = "<p>Hello, {{name}}! Welcome to {{place}}.</p>";
let result = do_html!(template, name = "Dear", place = "CANS Template");
assert_eq!(result, "<p>Hello, Dear! Welcome to CANS Template.</p>");
