Struct AnyObj 

pub struct AnyObj { /* private fields */ }

A type-erased wrapper for a reference.

Implementations

impl AnyObj

pub fn new<T>(data: T) -> Result<Self>

where T: Any,

Construct an Any that wraps an owned object.

Examples

use rune::Value;
use rune::runtime::AnyObj;
use rune::alloc::String;

let string = String::try_from("Hello World")?;
let string = AnyObj::new(string)?;
let string = Value::from(string);

let string = string.into_shared::<String>()?;
assert_eq!(string.borrow_ref()?.as_str(), "Hello World");

pub fn take(self) -> Result<Self, AnyObjError>

Take the interior value and return a handle to the taken value.

pub fn borrow_ref<T>(&self) -> Result<BorrowRef<'_, T>, AnyObjError>

where T: Any,

Get a reference to the interior value while checking for shared access.

This prevents other exclusive accesses from being performed while the guard returned from this function is live.

pub fn try_borrow_ref<T>(&self) -> Result<Option<BorrowRef<'_, T>>, AccessError>

where T: Any,

Try to borrow a reference to the interior value while checking for shared access.

Returns None if the interior type is not T.

This prevents other exclusive accesses from being performed while the guard returned from this function is alive.

pub fn try_borrow_mut<T>(&self) -> Result<Option<BorrowMut<'_, T>>, AccessError>

where T: Any,

Try to borrow a reference to the interior value while checking for exclusive access.

Returns None if the interior type is not T.

This prevents other exclusive accesses from being performed while the guard returned from this function is alive.

pub fn borrow_mut<T>(&self) -> Result<BorrowMut<'_, T>, AnyObjError>

where T: Any,

Returns some mutable reference to the boxed value if it is of type T.

pub fn type_hash(&self) -> Hash

Access the underlying type hash for the data.

pub fn type_info(&self) -> TypeInfo

Access full type info for the underlying type.

Trait Implementations

impl Clone for AnyObj

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnyObj

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for AnyObj

fn drop(&mut self)

Executes the destructor for this type.

impl From<AnyObj> for Value

Conversion from a AnyObj into a Value.

Examples

use rune::Value;
use rune::runtime::AnyObj;
use rune::alloc::String;

let string = String::try_from("Hello World")?;
let string = AnyObj::new(string)?;
let string = Value::from(string);

let string = string.into_shared::<String>()?;
assert_eq!(string.borrow_ref()?.as_str(), "Hello World");

fn from(value: AnyObj) -> Self

Converts to this type from the input type.

impl FromValue for AnyObj

fn from_value(value: Value) -> Result<Self, RuntimeError>

Try to convert to the given type, from the given value.

impl ToValue for AnyObj

fn to_value(self) -> Result<Value, RuntimeError>

Convert into a value.

impl TryClone for AnyObj

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<()>

Performs copy-assignment from source.
