Chat actions are what appear at the top of the screen
when users are typing, sending files, etc. You can
mimic these actions by using the
Stringrepresentation of this enum member.
String representation of this enum member.
In the case of regular enums, this is just the name of the member.
In the case of flag enums, it's the names joined by vertical bars, or "None",
if the value is zero.
If an enum's value doesn't match a member's value, the raw value is returned as a string.
Color::Red.to_s # => "Red" IOMode::None.to_s # => "None" (IOMode::Read | IOMode::Write).to_s # => "Read | Write" Color.new(10).to_s # => "10"
