Maps ​

The Jule maps are using std::unordered_map with custom hash algorithm which is FNV1 currently. The internal std::unordered_map buffer available via the buffer field of the jule::Map.

The using of jule::Map is too similar to using of std::unordered_map.

For example:

jule::Map<jule::Int, jule::Str> map = {
    {0, "Hello"},
    {1, "World"},
    {2, "Foo"},
    {3, "Bar"},
};
map.del(2);
map.clear();

Lookup ​

Jule has lookup assignments for lookup maps. In jule::Map type, the lookup method is equivalent for this.

For example:

jule::Map<jule::Int, jule::Str> map = {
    {0, "Hello"},
    {1, "World"},
    {2, "Foo"},
    {3, "Bar"},
};
jule::Str value;
jule::Bool ok;
map.lookup(3, &value, &ok);
if (ok) {
    jule::outln(value);
}
