# 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`
