Struct ComponentEntry 

pub struct ComponentEntry {
    pub key: Identifier,
    pub expected_discriminant: ComponentDataDiscriminant,
    pub network_reader: NetworkReader,
    pub network_writer: NetworkWriter,
    pub nbt_reader: NbtReader,
    pub nbt_writer: NbtWriter,
}

Metadata for a registered component type.

Contains the component’s key and all serialization functions needed to read/write the component for network and persistent storage.

Fields

key: Identifier

The component’s identifier (e.g., “minecraft:damage”)

expected_discriminant: ComponentDataDiscriminant

Expected discriminant for this component type

network_reader: NetworkReader

Network protocol reader

network_writer: NetworkWriter

Network protocol writer

nbt_reader: NbtReader

NBT storage reader

nbt_writer: NbtWriter

NBT storage writer

Implementations

impl ComponentEntry

pub fn new( key: Identifier, expected_discriminant: ComponentDataDiscriminant, network_reader: NetworkReader, network_writer: NetworkWriter, nbt_reader: NbtReader, nbt_writer: NbtWriter, ) -> Self

Creates a new component entry with all serialization functions.

pub fn validates(&self, data: &ComponentData) -> bool

Validates that a ComponentData value matches the expected type for this component.

Returns true if the data is valid for this component type, false otherwise. This prevents plugins from setting wrong types on vanilla components.
