# Struct openssl::ex_data::Index [−] [src]

    pub struct Index<T, U>(_, _);

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

### `impl<T, U> Index<T, U>` [src]

#### `pub unsafe fn from_raw(idx: c_int) -> Index<T, U>` [src]

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`.

#### `pub fn as_raw(&self) -> c_int` [src]
