std::map

std::map provides associative containers:

• HashMap(K, V) (unordered, hash table),
• TreeMap(K, V) (ordered, red-black tree).

Full reference: map.

Notes#

• Supported forms: usable in Silk currently with documented limits.
• Full reference: map

Importing#

import std::map;

Examples#

Example: HashMap(u64, int) basic usage#

import std::map;
import std::result;
import std::memory;

type Map = std::map::HashMap(u64, int);
type InitResult = std::result::Result(Map, std::memory::AllocFailed);

fn main () -> int {
  match (Map.init(16)) {
    InitResult::Ok(map) => {
      let mut m: Map = map;
      m.put(1, 10);
      let v: int = m.get(1) ?? 0;
      m.drop();
      return v;
    },
    InitResult::Err(_) => {
      return 2;
    },
  }
}
