CodeIteratorResult

Enum CodeIteratorResult 

Source
#[repr(C, usize)]
pub enum CodeIteratorResult<'p> { NullHandlePointer, Ok { handle: Box<CodeIteratorHandle<'p>>, }, Err(OwnedBytes), }
Expand description

A result type returned from FFI functions that create an code hash iterator

Variants§

§

NullHandlePointer

The caller provided a null pointer to a proof handle.

§

Ok

Building the iterator was successful and the iterator handle is returned

Fields

§handle: Box<CodeIteratorHandle<'p>>

An opaque pointer to the CodeIteratorHandle. The value should be freed with fwd_code_hash_iter_free

§

Err(OwnedBytes)

An error occurred and the message is returned as an OwnedBytes.

The caller must call fwd_free_owned_bytes to free the memory associated with this error.

fn value_size_sum_iter<'item>(iterator: impl Iterator<Item = &'item T>) -> usize
where T: 'item,

The total sum of the sizes of all values in the given iterator, in bytes. This is default-implemented by computing ValueSize::value_size on every element and summing them. For Sized types, a more potentially efficient implementation using Iterator::count is provided. If you are implementing this trait manually, it is unlikely to be more efficient to provide a manual implementation here. Read more

For Sized types, a usually more efficient implementation using ExactSizeIterator::len is provided. If you are implementing this trait manually, it is unlikely to be more efficient to provide a manual implementation here. Read more
