pub trait UnsafeToRef {
type Guard: 'static;
// Required method
unsafe fn unsafe_to_ref<'a>(
value: Value,
) -> Result<(&'a Self, Self::Guard), RuntimeError>;
}Expand description
Unsafe to ref coercion.
Required Associated Types§
Required Methods§
Sourceunsafe fn unsafe_to_ref<'a>(
value: Value,
) -> Result<(&'a Self, Self::Guard), RuntimeError>
unsafe fn unsafe_to_ref<'a>( value: Value, ) -> Result<(&'a 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", so this trait is not object safe.
