# Function transmute_unchecked

Source

    pub const unsafe fn transmute_unchecked<Src, Dst>(src: Src) -> Dst

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

Like `transmute`, but even less checked at compile-time: rather than giving an error for `size_of::<Src>() != size_of::<Dst>()`, it’s Undefined Behavior at runtime.

Prefer normal `transmute` where possible, for the extra checking, since both do exactly the same thing at runtime, if they both compile.

This is not expected to ever be exposed directly to users, rather it may eventually be exposed through some more-constrained API.
