hex.read_hex (arity 2)

Effectively:  dst = *ptr
dst is a hex. ptr is a hex[:w/4] that holds an address, which we assume is dw-aligned.

Signature

def read_hex dst, ptr { ... }

Defined in hex/pointers/read_pointers.fj — lines 9–12 (view on GitHub).

Complexity

• Time: w(0.75@+ 5) + 7@+13

• Space: w(0.75@+29) + 7@+48
