Struct EntityDataSerializerRegistry 

pub struct EntityDataSerializerRegistry {
    entries_by_id: Vec<EntityDataSerializerEntryRef>,
    entries_by_key: FxHashMap<Identifier, usize>,
    allows_registering: bool,
}

Registry of entity data serializers.

The serializer ID is determined by registration order, which must match vanilla’s EntityDataSerializers.java exactly.

Fields

entries_by_id: Vec<EntityDataSerializerEntryRef>

Serializer entries in registration order (index = ID).

entries_by_key: FxHashMap<Identifier, usize>

Map from key to ID for fast lookup.

allows_registering: bool

Whether registration is still allowed.

Implementations

impl EntityDataSerializerRegistry

pub fn new() -> Self

Create a new empty registry.

pub fn register(&mut self, key: Identifier, writer: EntityDataWriter)

Register a serializer with its writer function. ID is determined by registration order.

Panics

Panics if the registry has been frozen or if the key is already registered.

pub fn get_writer(&self, id: i32) -> Option<EntityDataWriter>

Get the writer function for a serializer by protocol ID.
