A trait for objects which can be converted or resolved to one or more
This trait is used for generic address resolution when constructing network objects. By default it is implemented for the following types:
This trait allows constructing network objects like
UdpSocket easily with values of various types for the bind/connection
address. It is needed because sometimes one type is more appropriate than
the other: for simple uses a string like
"localhost:12345" is much nicer
than manual construction of the corresponding
SocketAddr, but sometimes
SocketAddr value is the main source of the address, and converting it to
some other type (e.g., a string) just for it to be converted back to
SocketAddr in constructor methods is pointless.
Addresses returned by the operating system that are not IP addresses are silently ignored.
type Iter: Iterator<Item = SocketAddr>
Returned iterator over socket addresses which this type may correspond to.
fn to_socket_addrs(&self) -> Result<Self::Iter>
Converts this object to an iterator of resolved
The returned iterator may not actually yield any values depending on the outcome of any resolution performed.
Note that this function may block the current thread while resolution is performed.
