pub unsafe trait Context: Sealed {
    const FLAGS: u32;
    const DESCRIPTION: &'static str;

    // Required method
    unsafe fn deallocate(ptr: *mut u8, size: usize);
}

A trait for all kinds of contexts that lets you define the exact flags and a function to deallocate memory. It isn’t possible to implement this for types outside this crate.

Required Associated Constants

const FLAGS: u32

Flags for the ffi.

const DESCRIPTION: &'static str

A constant description of the context.

unsafe fn deallocate(ptr: *mut u8, size: usize)

A function to deallocate the memory when the context is dropped.
