Function parse_command_with_prefix 

pub fn parse_command_with_prefix<'a, N>(
    prefix: &str,
    text: &'a str,
    bot_name: N,
) -> Option<(&'a str, Vec<&'a str>)>
where
    N: AsRef<str>,

Parses a string into a command with args (custom prefix).

prefix: symbols, which denote start of a command.

Example

use teloxide_ng::utils::command::parse_command_with_prefix;

let text = "!mute 5 hours";
let (command, args) = parse_command_with_prefix("!", text, "").unwrap();
assert_eq!(command, "mute");
assert_eq!(args, vec!["5", "hours"]);

If the name of a bot does not match, it will return None:

use teloxide_ng::utils::command::parse_command_with_prefix;

let result = parse_command_with_prefix("!", "!ban@MyNameBot1 3 hours", "MyNameBot2");
assert!(result.is_none());
