Implementations

impl RawHandle

pub unsafe fn trust<T>(self, stadium: &Stadium<'_>) -> Handle<T>

Recreate an Handle from this RawHandle.

Safety

• The generic type parameter T must be the same as the original Handle that was used to produce this RawHandle.
• The given Stadium must be the one associated with the original handle.

Examples

let mut builder = stadium::builder();
let handle = builder.insert(5i32);
let stadium = builder.build();

let raw_handle = handle.raw();

// SAFETY: The handle was given by the builder that created the stadium and was
// created for a `i32`.
let handle = unsafe { raw_handle.trust::<i32>(&stadium) };

assert_eq!(stadium[handle], 5);

pub unsafe fn trust_with_builder<T>(self, builder: &Builder<'_>) -> Handle<T>

Recreate an Handle from this RawHandle.

Safety

• The generic type parameter T must be the same as the original Handle that was used to produce this RawHandle.
• The given Builder must be the one associated with the original handle.

Examples

let mut builder = stadium::builder();
let raw_handle = builder.insert(5i32).raw();

// SAFETY: The handle was given by this builder and was created for a `i32`.
let handle = unsafe { raw_handle.trust_with_builder::<i32>(&builder) };

let stadium = builder.build();
assert_eq!(stadium[handle], 5);
