Struct NativeChild 

pub struct NativeChild(/* private fields */);

One retained child of a component’s native subtree — the handle a component keeps in its NativeComponent::State when it wants to drive that child later (module doc’s A component owns its own native subtree).

Built only through ComponentCtx::retain_child. Dropping it is the release — DeleteGlobalRef on Android, Retained’s own Drop on iOS and macOS — and State is dropped immediately after NativeComponent::dispose returns, so a child is released with its parent by construction rather than by remembering to.

A child you never talk to again needs none of this: the platform parent already owns it.

Implementations

impl NativeChild

pub fn identity(&self) -> u64

This child’s stand-in identity — what a test asserts against.
