Struct fuchsia_inspect_derive::IOwned

pub struct IOwned<R: Render> { /* private fields */ }

Generic smart pointer which owns an inspect subtree (either a Node or a Property) for the duration of its lifetime. It dereferences to the user-provided base type (similar to Arc and other smart pointers). This type should rarely be used declared explictly. Rather, a specific smart pointer (such as IValue) should be used.

Implementations

impl<R: Render> IOwned<R>

pub fn new(value: R::Base) -> Self

Construct the smart pointer but don’t populate any inspect state.

pub fn attached(value: R::Base, parent: &Node, name: impl AsRef<str>) -> Self

Construct the smart pointer and populate the inspect state under parent[name].

pub fn as_mut(&mut self) -> IOwnedMutGuard<'_, R>

Returns a RAII guard which can be used for mutations. When the guard goes out of scope, the new inspect state is published.

pub fn iset(&mut self, value: R::Base)

Set the value, then update inspect state.

pub fn into_inner(self) -> R::Base
