Trait RawBorrowMut 

pub trait RawBorrowMut<T> {
    // Required method
    unsafe fn raw_borrow_mut<'a>(
        input: *mut T,
    ) -> Result<&'a mut Self, UnexpectedNullPointerError>;
}

Trait to create mutable borrowed references to type T, from a raw pointer to a T. Note that this is implemented for all types.

Required Methods

unsafe fn raw_borrow_mut<'a>( input: *mut T, ) -> Result<&'a mut Self, UnexpectedNullPointerError>

Get a mutable reference on the value behind the pointer or return an error if the pointer is null.

Safety

As this is using *mut T:as_ref() this is unsafe for exactly the same reasons.

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.

Implementors

impl<T> RawBorrowMut<T> for T

Trait that allows obtaining a mutable borrowed reference to a type T from a raw pointer to T
