i have a struct that contains a field []u8. when i try to init it by using [_]u8{...} i get this error
#array literal requires address-of operator (&) to coerce to slice type '[]u8'

it's like the error says: you have an array literal, to make it a slice you have to prefix it with &

if the field is of type []u8, that still won't work; did you meant to use []const u8?

tried with const too

This error has confused quite a few people over the past couple of years, and should probably read more like:
error: array literal cannot coerce into slice type
note: use '&[_]u8{}' or '&.{}' if you mean to make a slice.
using const and & should work
and yeah that error message is a much clearer explanation

It will also work with a mutable slice type, if the array literal has no elements.
