Trait InquireLength 

pub trait InquireLength {
    // Required method
    fn inquire_length(&self) -> usize;
}

Custom trait to call correct method to retrieve input length.

The method can vary depending on the type of input.

String inputs should count the number of graphemes, via .graphemes(true).count(), instead of the number of bytes via .len(). While simple slices should keep using .len()

Required Methods

String inputs should count the number of graphemes, via .graphemes(true).count(), instead of the number of bytes via .len(). While simple slices keep using .len()

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
