Expand description

A Rust-side argument to a safe wrapper around a printf(3)-like function.

This is a sealed trait; consumers of this crate are not allowed to create their own impls in order to unconditionally preserve safety.

Required Associated Types

The C type corresponding to Self that we should really send as an argument to a printf(3)-like function.

Provided Associated Constants

Whether the type is consistent with C’s char.

Whether the type is consistent with C’s short int.

Whether the type is consistent with C’s int.

Whether the type is consistent with C’s long int.

Whether the type is consistent with C’s long long int.

Whether the type is consistent with C’s size_t.

Whether the type is consistent with C’s intmax_t.

Whether the type is consistent with C’s ptrdiff_t.

Whether the type is a signed integer type, as opposed to unsigned.

Whether the type is floating-point.

Whether the type is a null-terminated string.

Whether the type is a pointer.

Required Methods

Converts self to a value suitable for sending to printf(3).
