Just as the title suggests, what is the recommended way of converting a
sequence of four uint8's into a uint32? Or even more specifically, how would
you convert four consecutive bytes within a larger sequence into a uint32? At
the moment, I'm doing this:
var offset = 0
var x = (cast[int32](buf[offset]) shl 0) or
(cast[int32](buf[offset+1]) shl 8) or
(cast[int32](buf[offset+2]) shl 16) or
(cast[int32](buf[offset+3]) shl 24)
but this doesn't seem particularly efficient since it involves four individual
casts and bit ops. Any suggestions? Thanks.
