//! This module provides any char matcher like "." in regex.
//! - `AnyChar`: matches with any charactor.

use super::Matcher;

/// Match with any one charactor.
/// # Example
/// ```
/// use rexify::Matcher;
/// use rexify::Rex;
/// use rexify::any_char::AnyChar;
///
/// let rex = Rex::new(vec![
///     Box::new(AnyChar::new())
/// ]);
///
/// assert_eq!(rex.find("a"), Some(0));
/// ```
