Cap

Returns the number of allocated slots.

Module: Std::HashMap

Signature

func Cap(self) -> uint;

Returns

uint — the number of slots currently allocated. Always greater than Len; the map grows (doubling its capacity) before it fills up.

Description

Capacity is an implementation detail of how the map is stored — most code only needs Len. It can be useful for diagnostics or for understanding growth behavior.

Example

import Std::HashMap::*;

// After Init, Cap() is the default of 16.
