primitives

Describe the feature you would like

The primitives library defines the fixed_bytes_macros! {} internal utility macro, which in turn is used to define exported macros such as address!() for compile-time values. The latter takes in a hex-encoded string literal, which is then represented as an Address value.

Currently the hex-literal crate is responsible for translating hex-encoded string literals into byte arrays in compile time. It is not feature-complete though, notably it lacks the support for "0x" prefix.

There exists an alternative hexlit crate which seems to be a more recent drop-in replacement for hex-literal, and which does support additional features such as "0x" prefix, as well as some extra kinds of formatting characters, such as hyphen '-' and underscore '_'.
