Trait Value 

pub unsafe trait Value: Sized {
    // Required methods
    fn into_raw(self) -> u64;
    unsafe fn from_raw_unchecked(raw: u64) -> Self;
}

Values that can be safely stored in a SequentialMap.

Safety

Implementer must guarantee that Self has the same memory layout as a u64.

Required Methods

fn into_raw(self) -> u64

Erase the type of this value, returning a u64.

unsafe fn from_raw_unchecked(raw: u64) -> Self

Safety

Caller must guarantee that:

• raw was created by a previous Value::into_raw call.
• from_raw is called at most once for each Value::into_raw call.
• There are no live borrows when Value::from_raw_unchecked is called.

Dyn Compatibility

This trait is not dyn compatible.

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