Hi!
I've been playing a bit with Nim's sets to check if I can use them for my
application.
In particular, I have to deal with a huge amount of sets, so I look for as much
memory efficiency as possible.
>From what I have seen, it seems the standard `set` would fit my needs. This
>would be a simplification for my _Container_ object:
include prelude
type Container = ref object
max_val: int
sets: HashSet[set[uint16]]
proc newContainer(max_val: int): Container =
Container(
max_val: max_val,
sets: HashSet[set[uint16]](),
)
proc add(c: Container, val: set[uint16]) =
c.sets.incl(val)
proc remove(c: Container, val: set[uint16]) =
c.sets.excl(val)
proc show(c: Container) =
echo c.sets
Run
I would like to limit the size of the inner sets as much as possible. I have
seen that this can be achieved through Subranges, but I couldn't find out how
could this be done in a dynamic way. For example, in my case, I would like to
replace the `uint16` type with a more restricted bound according to `max_val`,
as for most cases `max_val` will be much smaller than `high(uint16)`.
Thank you for your time and your help!
