Trait windows::Abi[−][src]

pub unsafe trait Abi: Sized {
    type Abi;
    fn abi(&self) -> Self::Abi { ... }

    fn set_abi(&mut self) -> *mut Self::Abi { ... }

    unsafe fn from_abi(abi: Self::Abi) -> Result<Self> { ... }

    fn drop_param(_: &mut Param<'_, Self>) { ... }
}

Provides a generic way of referring to and converting between a Rust object and its ABI equivalent.

This trait is automatically used by the generated bindings and should not be used directly.

Associated Types

type Abi[src]

The abi representation of the implementing type.

SAFETY: Self and Abi must have the same exact in-memory representation.

Provided methods

fn abi(&self) -> Self::Abi[src]

Casts the Rust object to its ABI type without copying the object.

fn set_abi(&mut self) -> *mut Self::Abi[src]

Returns a pointer for setting the object’s value via an ABI call.

unsafe fn from_abi(abi: Self::Abi) -> Result<Self>[src]

Casts the ABI representation to a Rust object by taking ownership of the bits.

fn drop_param(_: &mut Param<'_, Self>)[src]
