pub struct UnsafeArg {
_private: (),
}
🔬This is a nightly-only experimental API. (
fmt_internals
)Expand description
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.
