Trait OptionCastUncheckedMutExt 

pub trait OptionCastUncheckedMutExt<'a> {
    // Required method
    unsafe fn cast_unchecked_mut<T>(self) -> Option<&'a mut T>;
}

Required Methods

unsafe fn cast_unchecked_mut<T>(self) -> Option<&'a mut T>

Casts a mutable untyped heap reference ([`&mut void]) into a typed one.

Safety

Horribly unsafe if T doesn’t point to an initialised instance of T.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
