Enum InputSource 

pub enum InputSource {
    Terminal,
    Custom(Pin<Box<dyn AsyncRead + Send + Unpin>>),
}

Represents different input sources that the InputHandler can read from.

This enum allows the program to read input from either the standard crossterm event stream (for regular terminal input) or from a custom async reader.

Variants

Terminal

Standard terminal input using crossterm’s event stream. This is the default and handles keyboard, mouse, and resize events.

Custom(Pin<Box<dyn AsyncRead + Send + Unpin>>)

Custom input reader that implements AsyncRead + Send + Unpin. This allows reading input from files, network streams, or other sources. The custom reader is expected to provide line-based input.
