Struct InplaceValue 

pub struct InplaceValue<'a> { /* private fields */ }

Engine-issued permission to attempt in-place mutation of one value.

The engine issues it only when the current ownership path permits reuse.

Implementations

impl<'a> InplaceValue<'a>

pub fn as_value(&self) -> &MapValue

Borrow the value without its in-place capability.

pub fn to_owned(&self) -> Any

Retain an owning copy of the value.

Retaining an object creates an alias. The default in-place helper rechecks uniqueness and automatically falls back to copying.

Methods from Deref<Target = MapValue>

pub fn to_owned(&self) -> Any

Copy this borrowed value into an owning Any.

pub fn cast<R: AnyCompatible>(&self) -> Option<R>

Convert the value into an owned typed handle.

pub fn type_index(&self) -> i32

Runtime type index stored in this value.

pub fn as_node<N: ObjectCore>(&self) -> Option<&N>

Borrow the value as node type N if it is an instance of that type.

Trait Implementations

impl Deref for InplaceValue<'_>

type Target = StructuralValue

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
