Struct std::iter::Counter

pub struct Counter<A> {
    state: A,
    step: A,
}

An infinite iterator starting at start and advancing by step with each iteration

Trait Implementations

Returns a copy of the value. The contents of owned pointers are copied to maintain uniqueness, while the contents of managed pointers are not copied.

Advance the iterator and return the next value. Return None when the end is reached.

Return a lower bound and upper bound on the remaining length of the iterator.

The common use case for the estimate is pre-allocating space to store the results.
