+pub use crate::{Error, SequenceIterator};
+
+/// An Iterator over binary data, parsing elements of type `T`
+///
+/// This helps parsing `SET OF` items of type `T`. The type of parser
+/// (BER/DER) is specified using the generic parameter `F` of this struct.
+///
+/// Note: the iterator must start on the set *contents*, not the set itself.
+///
+/// # Examples
+///
+/// ```rust
+/// use asn1_rs::{DerParser, Integer, SetIterator};
+///
+/// let data = &[0x30, 0x6, 0x2, 0x1, 0x1, 0x2, 0x1, 0x2];
+/// for (idx, item) in SetIterator::<Integer, DerParser>::new(&data[2..]).enumerate() {
+///     let item = item.unwrap(); // parsing could have failed
+///     let i = item.as_u32().unwrap(); // integer can be negative, or too large to fit into u32
+///     assert_eq!(i as usize, idx + 1);
+/// }
+/// ```
