Struct IMediaSeeking 

pub struct IMediaSeeking(/* private fields */);

IMediaSeeking COM interface.

Automatically calls IUnknown::Release when the object goes out of scope.

Examples

use winsafe::{self as w, prelude::*};

let graph_builder: w::IGraphBuilder; // initialized somewhere

let media_seeking = graph_builder
    .QueryInterface::<w::IMediaSeeking>()?;
