Mention that users need to change HashMap and HashSet initializations in 0.16 #2045
Description
Methods that are affected:
new->defaultfrom->from_iter- possibly others? Note from @Victoronz: "To find every DefaultHashBuilder specific impl, the docs of hashbrown should be easily searchable"
Examples
use bevy::platform_support::collections::HashMap;
struct SomeHashMap(HashMap<u32, u32>);
fn main() {
// This fails to compile (same for HashSet):
let some_hash_map = SomeHashMap(HashMap::new());
// This works fine (same for HashSet):
let some_hash_map = SomeHashMap(HashMap::default());
}And
use bevy::platform_support::collections::HashSet;
struct SomeHashSet(HashSet<u32>);
fn main() {
// This fails to compile:
let some_hash_set = SomeHashSet(HashSet::from([1, 2, 3]));
// This works fine:
let some_hash_set = SomeHashSet(HashSet::from_iter([1, 2, 3]));
}
