Struct domain::base::scan::IterScanner

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

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.

Implementations

impl<Iter: Iterator, Octets> IterScanner<Iter, Octets>

pub fn new<I: IntoIterator<IntoIter = Iter>>(iter: I) -> Self

Creates a new scanner from an iterator.

pub fn is_exhausted(&mut self) -> bool

Returns whether the iterator is exhausted.

Trait Implementations

impl<Iter, Item, Octets> Scanner for IterScanner<Iter, Octets>

where Item: AsRef<str>, Iter: Iterator<Item = Item>, Octets: FromBuilder, <Octets as FromBuilder>::Builder: EmptyBuilder + Composer,

type Octets = Octets

The type of octet sequences returned by the scanner.

type OctetsBuilder = <Octets as FromBuilder>::Builder

The octets builder used internally and returned upon request.

type Dname = Dname<Octets>

The type of a domain name returned by the scanner.

type Error = StrError

The error type of the scanner.

fn has_space(&self) -> bool
