🔬This is a nightly-only experimental API. (fmt_internals)

These are the lang items used by format_args!().

Structs

• ArgumentExperimental
  This struct represents the generic “argument” which is taken by format_args!(). It contains a function to format the given value. At compile time it is ensured that the function and the value have the correct types, and then this struct is used to canonicalize arguments to one type.
• PlaceholderExperimental
• UnsafeArgExperimental
  This struct represents the unsafety of constructing an Arguments. It exists, rather than an unsafe function, in order to simplify the expansion of format_args!(..) and reduce the scope of the unsafe block.
