Trait Implementations

impl Clone for IStream

pub fn clone(&self) -> IStream

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IStream

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

Formats the value using the given formatter.

impl<'_> From<&'_ IStream> for ISequentialStream

pub fn from(value: &IStream) -> ISequentialStream

Performs the conversion.

impl From<IStream> for ISequentialStream

pub fn from(value: IStream) -> ISequentialStream

Performs the conversion.

impl Interface for IStream

type Vtable = IStream_abi

pub const IID: Guid

unsafe fn vtable(&self) -> &Self::Vtable

Safety

unsafe fn assume_vtable<T>(&self) -> &<T as Interface>::Vtable where
    T: Interface, 

Safety

unsafe fn query(&self, iid: *const Guid, interface: *mut *mut c_void) -> HRESULT

Safety

fn cast<T>(&self) -> Result<T, Error> where
    T: Interface, 

Attempts to cast the current interface to another interface using QueryInterface. The name cast is preferred to query because there is a WinRT method named query but not one named cast.

fn downgrade(&self) -> Result<Weak<Self>, Error>

Attempts to create a Weak reference to this object.

impl PartialEq<IStream> for IStream

pub fn eq(&self, other: &IStream) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &IStream) -> bool

This method tests for !=.
