Struct concat::Concat
[−]
[src]
pub struct Concat<I> where I: Iterator, I::Item: Read {
// some fields omitted
}
Methods
impl<I> Concat<I> where I: Iterator, I::Item: Read
[src]
fn current(&self) -> Option<&I::Item>
Returns a reference to the item last read, or None if the iterator has been exhausted.
This is useful for error handling and reporting: if a read operation fails, the reference returned will point to the item which caused the the error.
