# [−][src]Function core::intrinsics::init

    pub unsafe extern "rust-intrinsic" fn init<T>() -> T

Deprecated since 1.38.0:

superseded by MaybeUninit, removal planned

🔬 This is a nightly-only experimental API. (`core_intrinsics`)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Creates a value initialized to zero.

`init` is unsafe because it returns a zeroed-out datum, which is unsafe unless `T` is `Copy`. Also, even if T is `Copy`, an all-zero value may not correspond to any legitimate state for the type in question.

The stabilized version of this intrinsic is `std::mem::zeroed`.
