Struct Return

#[repr(C)]
pub struct Return { /* private fields */ }

Implementations

impl Return

pub fn from_fields(loc: impl Into<Location>, value: impl Into<Expr>) -> Self

Lossless complete-field allocation.

impl Return

pub fn new(value: impl Into<Expr>, loc: impl Into<Location>) -> Self

Return value from the enclosing function (C++ Return(value, loc)).

Trait Implementations

impl AnyCompatible for Return

unsafe fn is_undefined(field: *const Self) -> bool

Whether field, which holds a value of this type or all-zero bytes, holds all-zero bytes that are no value of this type, as a null object reference, a string of type index None or a zero device type: a field that a creator left undefined for reflection to set, as C++ UnsafeInit leaves a reference undefined (null). Unlike a C++ undefined reference, it is no value; a nullable reference is Option<T>, whose None is a defined value.

fn type_str() -> String

the type string of the type

unsafe fn copy_to_any_view(src: &Self, data: &mut TVMFFIAny)

the value to copy to TVMFFIAny

unsafe fn check_any_strict(data: &TVMFFIAny) -> bool

unsafe fn copy_from_any_view_after_check(data: &TVMFFIAny) -> Self

Copy value from TVMFFIAny after checking caller must ensure that the value is compatible with the type

unsafe fn move_to_any(src: Self, data: &mut TVMFFIAny)

consume the value to move to Any

unsafe fn move_from_any_after_check(data: &mut TVMFFIAny) -> Self

the value to move from TVMFFIAny NOTE: pay very careful attention to avoid memory leak!

unsafe fn try_cast_from_any_view(data: &TVMFFIAny) -> Result<Self, ()>

try to cast the value from AnyView

fn get_mismatch_type_info(data: &TVMFFIAny) -> String

Get the type key of a type when TryCastFromAnyView fails.

fn type_schema() -> String

The type schema of the type: the JSON object C++ TypeTraits<T>::TypeSchema writes, which the type schemas of functions and fields embed.

fn to_any(&self) -> Any

Borrow self into an owned Any, increfing object-backed values.

impl<'a> ArgIntoRef for &'a Return

type Target = Return

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

impl ArgIntoRef for Return

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

impl Clone for Return

fn clone(&self) -> Return

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Deref for Return

type Target = ReturnObj

The resulting type after dereferencing.

fn deref(&self) -> &ReturnObj

Dereferences the value.

impl From<&Return> for Return

fn from(value: &Return) -> Self

Converts to this type from the input type.

impl From<&Return> for Stmt

fn from(value: &Return) -> Self

Converts to this type from the input type.

impl From<Return> for Stmt

fn from(value: Return) -> Self

Converts to this type from the input type.

impl<'a> IntoArgHolder for &'a Return

type Target = &'a Return

fn into_arg_holder(self) -> Self::Target

impl IntoArgHolder for Return

type Target = Return

fn into_arg_holder(self) -> Self::Target

impl ObjectRefCore for Return

type ContainerType = <ObjectArc<ReturnObj> as Deref>::Target

fn data(this: &Self) -> &ObjectArc<Self::ContainerType>

fn into_data(this: Self) -> ObjectArc<Self::ContainerType>

unsafe fn from_data(data: ObjectArc<Self::ContainerType>) -> Self

Construct a reference view from an owning container handle.

fn same_as<Other>(&self, other: &Other) -> bool

where Other: ObjectRefCore,

Return whether two object references point to the same allocation.

fn downcast_ref<T>(&self) -> Option<&T>

where T: ObjectCore,

Borrow the underlying object as T when its runtime type is T or a subtype.

impl TryFrom<Any> for Return

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Any) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> TryFrom<AnyView<'a>> for Return

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: AnyView<'a>) -> Result<Self, Self::Error>

Performs the conversion.
