Trait flatk::TrustedRandomAccess[−][src]

pub unsafe trait TrustedRandomAccess: ExactSizeIterator {
    unsafe fn get_unchecked(&mut self, index: usize) -> Self::Item;

    fn may_have_side_effect() -> bool { ... }
}
Expand description

An iterator whose items are random-accessible efficiently

Safety

The iterator’s .len() and size_hint() must be exact. .len() must be cheap to call.

.get_unchecked() must return distinct mutable references for distinct indices (if applicable), and must return a valid reference if index is in 0..self.len().

Required methods

Gets the element at the given index from this iterator.

Safety

The index must not exceed the number of items produced by this iterator to avoid undefined behaviour.

Provided methods

Returns true if getting an iterator element may have side effects. Remember to take inner iterators into account.
