# Function glib::spaced_primes_closest [−][src]

pub fn spaced_primes_closest(num: u32) -> u32

## Expand description

Gets the smallest prime number from a built-in array of primes which
is larger than `num`

. This is used within GLib to calculate the optimum
size of a `GHashTable`

.

The built-in array of primes ranges from 11 to 13845163 such that each prime is approximately 1.5-2 times the previous prime.

`num`

a `guint`

# Returns

the smallest prime number from a built-in array of primes
which is larger than `num`
