Struct domain::base::scan::IterScanner

source ·
pub struct IterScanner<Iter: Iterator, Octets> { /* private fields */ }
Expand description

A simple scanner atop an iterator of strings.

The type is generic over the iterator as well as the octets sequence to use for returned data. The types associated octets builder is used to create values.
