Struct c_bridge::RustBox

#[repr(transparent)]
pub struct RustBox(_);

An interface to work with FfiObjects containing a boxed Rust object

Methods

impl RustBox

pub fn as_ref(&self) -> &(dyn Any + 'static)

The underlying element as reference

pub fn as_mut(&mut self) -> &mut (dyn Any + 'static)

The underlying element as mutable reference

pub fn move_into_box(self) -> Result<Box<dyn Any + 'static>, Self>

Moves the underlying memory from the payload out of the FfiObject and creates a Box from it

Note: this only works if the Rust object was created using from_object (which should almost always be the case)

Trait Implementations

impl From<RustBox> for FfiObject

fn from(boxed: RustBox) -> Self

Performs the conversion.

impl<T: Any + 'static> From<Box<T>> for RustBox

fn from(boxed: Box<T>) -> Self

Creates a new Box from object and encapsulates it into a wrapped and owned FfiObject

impl TryFrom<FfiObject> for RustBox

type Error = FfiObject

The type returned in the event of a conversion error.

fn try_from(object: FfiObject) -> Result<Self, Self::Error>

Converts object into the Rust box if it has the correct type and is not empty
