Struct Index 

Source 
pub struct Index<T, U>(/* private fields */);
Expand description

A slot in a type’s “extra data” structure.

It is parameterized over the type containing the extra data as well as the type of the data in the slot.

Implementations§

Source§

impl<T, U> Index<T, U>

Source

pub unsafe fn from_raw(idx: c_int) -> Index<T, U>

Creates an Index from a raw integer index.

§Safety

The caller must ensure that the index correctly maps to a U value stored in a T.

Source

pub fn as_raw(&self) -> c_int

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
