fn from(value: &IAudioBass) -> Self

Converts to this type from the input type.

impl From<&IAudioMidrange> for IPerChannelDbLevel

fn from(value: &IAudioMidrange) -> Self

Converts to this type from the input type.

impl From<&IAudioTreble> for IPerChannelDbLevel

fn from(value: &IAudioTreble) -> Self

Converts to this type from the input type.

impl From<&IAudioVolumeLevel> for IPerChannelDbLevel

fn from(value: &IAudioVolumeLevel) -> Self

Converts to this type from the input type.

impl From<&IPerChannelDbLevel> for IUnknown

fn from(value: &IPerChannelDbLevel) -> Self

Converts to this type from the input type.

impl From<IAudioBass> for IPerChannelDbLevel

fn from(value: IAudioBass) -> Self

Converts to this type from the input type.

impl From<IAudioMidrange> for IPerChannelDbLevel

fn from(value: IAudioMidrange) -> Self

Converts to this type from the input type.

impl From<IAudioTreble> for IPerChannelDbLevel

fn from(value: IAudioTreble) -> Self

Converts to this type from the input type.

impl From<IAudioVolumeLevel> for IPerChannelDbLevel

fn from(value: IAudioVolumeLevel) -> Self

Converts to this type from the input type.

impl Interface for IPerChannelDbLevel

const IID: Guid

type Vtable = IPerChannelDbLevel_abi

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

Returns the vtable for the current interface.

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

where T: Interface,

Returns the vtable for an assumed interface. The name comes from Box’s assume_init method as it assumes the vtable is implemented by the current interface’s vtable (e.g. a parent interface).

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.

impl PartialEq for IPerChannelDbLevel

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
