Why will Rust integer types be deprecated soon?

Question

I've noticed a deprecation note on the Rust std page next to u8, i8, u16 and so on:

What is going on, and what will the replacement be?

Answer 1

The types themselves aren't being deprecated, just the modules named e.g. std::i8 which contain constants. For example, std::i8::MIN is being replaced with i8::MIN (docs). The deprecation notice says:

Deprecating in a future Rust version: all constants in this module replaced by associated constants on i8
