readformat

The inverse of format!(). The format argument is the format string, and the s argument is the string to match the format against.

Examples:

• readf1("Hello, {}!", "Hello, world!") => Some("world")
• readf("I hope {} are doing {}!", "I hope you are doing well!") => Some(vec!["you", "well"])
• readf1("Goodbye, {}!", "Hello, world!") => None
