Detailed Description

Type used to invoke constructors that explicitly don't zero-initialize low level data structures.

Some system data structures like struct sigaction or siginfo_t are rather large. Zero initializing them could be costly if they are only used as system call output parameters, for example.

Since not initializing data structures can be risky it is better to explicitly request non-initialization. This is what this tag type is used for. libcosmos types that support this offer an overloaded construct that can be passed cosmos::no_init to request the non-initialization behaviour.
