Convert array to slice in Go

Question

This seems like it would be a fairly common thing and abundant examples across the interwebs, but I can\'t seem to find an example of how to convert an [32]byte

Answer 1

You can generally slice an array by its bounds with : :

var a [32]byte 
slice := a[:]

More generally, for the following array :

var my_array [LENGTH]TYPE

You can produce the slice of different sizes by writing :

my_array[START_SLICE:END_SLICE]

Omitting START_SLICE if it equals to the low bound and END_SLICE if equals to the high bound, in your case :

a[0:32] 

Produces the slice of the underlying array and is equivalent to :

a[0:]
a[:32]
a[:]
