Crate com[−][src]

Expand description

A helper crate for consuming and producing COM interfaces.

Example

To work with a COM interface it must first be declared:

/// Define an IAnimal interface
com::interfaces! {
    #[uuid("EFF8970E-C50F-45E0-9284-291CE5A6F771")]
    pub unsafe interface IAnimal: com::interfaces::IUnknown {
        unsafe fn Eat(&self) -> com::sys::HRESULT;
    }
}

To define a COM implementation class:

com::class! {
    pub class BritishShortHairCat: IAnimal {
        num_owners: u32,
    }

    impl IAnimal for BritishShortHairCat {
        fn Eat(&self) -> com::sys::HRESULT {
            println!("Eating...");
            com::sys::NOERROR
        }
    }
}
