Struct Registry 

pub struct Registry {
    pub components: Vec<ComponentInfo>,
}

Ordered built-in component reflection/serialization table. This is distinct from ECS registration: use Self::register for host extensions.

Fields

components: Vec<ComponentInfo>

Component metadata in Inspector/serialization order.

Implementations

impl Registry

pub fn register_world(&self, world: &mut World)

Registers every metadata type in a fresh world through host-owned callbacks. Needed when loading scenes containing permanent host extension components.

pub fn get(&self, name: &str) -> Option<&ComponentInfo>

Finds metadata by exact component name.

pub fn register<T: Component>(&mut self, world: &mut World)

Registers an editor-visible component in this table and a host world. Re-registering the same type is idempotent. Call only in permanent host code, because native library unloading would invalidate storage/callback vtables.

pub fn of_entity<'a>( &'a self, world: &World, entity: Entity, ) -> Vec<&'a ComponentInfo>

Metadata for components present on this entity, preserving registry order.

pub fn validate_entity(&self, world: &World, entity: Entity) -> Vec<String>

Reports registered component values that cannot round-trip through JSON. Unknown/runtime-only storages are ignored; stale handles return one diagnostic.

pub fn add_named( &self, world: &mut World, entity: Entity, name: &str, ) -> Result<bool, String>

Inserts a default named component only when it is absent. Returns whether insertion occurred; errors report unknown types or stale handles.

pub fn remove_named( &self, world: &mut World, entity: Entity, name: &str, ) -> Result<bool, String>

Removes a named component, enforcing its Inspector removal policy. Returns whether a value existed. Unknown/stale/non-removable requests fail.

pub fn copy_entity(&self, world: &mut World, from: Entity, to: Entity)

Copies every registered component from one entity to another (used for duplicate).

Trait Implementations

impl Default for Registry

fn default() -> Self

Returns the “default value” for a type.
