-// ConfigState houses the configuration options used by spew to format and

-// all top-level Formatter and Dump functionality. Each ConfigState instance
-// provides methods equivalent to the top-level functions.
-//
-// The zero value for ConfigState provides no indentation. You would typically
-// want to set it to a space or a tab.
-//
-// Alternatively, you can use NewDefaultConfig to get a ConfigState instance
-// with default settings. See the documentation of NewDefaultConfig for default
-// values.

- // receiver when the current type is not a pointer.
- //
- // NOTE: This might be an unsafe action since calling one of these methods
- // with a pointer receiver could technically mutate the value, however,
- // in practice, types which choose to satisify an error or Stringer
- // interface with a pointer receiver should not be mutating their state
- // inside these interface methods. As a result, this option relies on

- // a custom error or Stringer interface is invoked. The default, false,

- // the internals of the data type.

-addresses), %#v (adds types), and %#+v (adds types and pointer addresses) verb
-combinations. Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting. In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Typically this function shouldn't be called directly. It is much easier to make
-use of the custom formatter by calling one of the convenience functions such as
-c.Printf, c.Println, or c.Printf.

- * Circular data structures are detected and handled properly
- * Custom Stringer/error interfaces are optionally invoked, including

- a pointer receiver are optionally invoked when passing non-pointer

- * Byte arrays and slices are dumped like the hexdump -C command which
- includes offsets, byte values in hex, and ASCII output
