Instance Method Summary

• #affects_display? : Bool
• #background_color : String?
• #foreground_color : String?
• #generate_background_string(escape_code : EscapeCode | Nil) : String
• #ignorable : Bool
• #raw : String
• #string : String
• #styles : Array(Int32)
• #to_span(escape_code : EscapeCode | Nil) : String

  we take in the prior escape_code in part to know we have to end the prior code and in part to know what needs to be continued if it is ended.
