Get a Substring by Char Index and Length

Demonstrates how to use the GetRange method to get a substring by index and length.

Note: This example demonstrates the GetRange method which was added in Chilkat v9.5.0.87.

Rust

let sb = chilkat::StringBuilder::new();

// Load a file that contains this string:  0123456789ABCDEF
let _ = sb.load_file("qa_data/txt/remove_chars.txt", "utf-8").is_ok();

// Return "56789A" from the string.
// if removeFlag is true, the returned string is also removed from the sb.
let remove_flag = true;
let result = sb.get_range(5, 6, remove_flag).unwrap_or_default();

println!("{}", result);
println!("{}", sb.get_as_string().unwrap_or_default());

// Output is: 
// 
// 56789A
// 01234BCDEF
