Struct InRef 

pub struct InRef<'a, T: Type<T>>(/* private fields */);

A borrowed ABI-compatible input parameter.

Implementations

impl<T: Type<T>> InRef<'_, T>

pub fn is_null(&self) -> bool

Returns true if the argument is null.

pub fn ok(&self) -> Result<&T>

Returns the referenced value or E_POINTER if null.

pub fn as_ref(&self) -> Option<&T>

Returns the referenced value if non-null.

pub fn unwrap(&self) -> &T

Returns the referenced value.

Panics

Panics if the argument is null.

pub fn cloned(&self) -> Option<T>

Converts the argument to an Option<T> by cloning the reference.

Trait Implementations

impl<T: Type<T>> Default for InRef<'_, T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Type<T>> Deref for InRef<'_, T>

type Target = <T as Type<T>>::Default

The resulting type after dereferencing.

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

Dereferences the value.

impl<'a, T> From<&'a Option<T>> for InRef<'a, T>

where T: TypeKind<TypeKind = InterfaceType> + Type<T, InterfaceType>,

fn from(from: &'a Option<T>) -> Self

Converts to this type from the input type.

impl<'a, T: Type<T>> From<&'a T> for InRef<'a, T>

fn from(from: &'a T) -> Self

Converts to this type from the input type.

impl<'a, T> From<Option<&'a T>> for InRef<'a, T>

where T: TypeKind<TypeKind = InterfaceType> + Type<T, InterfaceType>,

fn from(from: Option<&'a T>) -> Self

Converts to this type from the input type.
