Trait UnsafeToMut 

pub trait UnsafeToMut {
    type Guard: 'static;

    // Required method
    unsafe fn unsafe_to_mut<'a>(
        value: Value,
    ) -> Result<(&'a mut Self, Self::Guard), RuntimeError>;
}

Unsafe to mut coercion.

Required Associated Types

type Guard: 'static

The raw guard returned.

Must only be dropped after the value returned from this function is no longer live.

Required Methods

unsafe fn unsafe_to_mut<'a>( value: Value, ) -> Result<(&'a mut Self, Self::Guard), RuntimeError>

Safety

Caller must ensure that the returned reference does not outlive the guard.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
