Function replace_placeholder 

pub fn replace_placeholder(
    input: &str,
    placeholder: &str,
    replacement: &str,
) -> String

Replaces placeholders in a string with specified replacement values.

This function takes a string containing placeholders in the format {{placeholder}} and replaces them with the specified replacement value. It uses regex pattern matching to find and replace all occurrences of the placeholder.

Arguments

• input - A string slice that contains the text with placeholders
• placeholder - A string slice representing the placeholder name (without braces)
• replacement - A string slice containing the value to replace the placeholder with

Returns

Returns a new String with all occurrences of the placeholder replaced with the replacement value.

Examples

let template = "Hello {{name}}! Welcome to {{place}}.";
let result = byteutils::string::replace_placeholder(template, "name", "John");
assert_eq!(result, "Hello John! Welcome to {{place}}.");

Panics

This function will panic if the regex pattern creation fails, which should only happen if the placeholder contains characters that make an invalid regex pattern.
