//! This module contains an enumeration `StringContentError` for representing possible errors
//! related to validation of string content. This includes checks for empty strings or strings that
//! consist only of blank spaces.
//!
//! The module also provides implementations of the `Debug` and `Display` traits for
//! `StringContentError`, enabling error representation in different formats.

use std::fmt::{Debug, Display, Formatter};

/// Represents possible errors related to string content validation.
pub enum StringContentError {
    /// Indicates the string is empty.
    Empty,
    /// Indicates the string contains only blank spaces. Includes the original string.
    Blank(String),

            StringContentError::Blank(value) => write!(f, "Blank(value = `{}`)", value.escape_debug()),
