# 1.0.0[−][src]Struct std::net::AddrParseError

    pub struct AddrParseError(_);

An error which can be returned when parsing an IP address or a socket address.

This error is used as the error type for the `FromStr` implementation for `IpAddr`, `Ipv4Addr`, `Ipv6Addr`, `SocketAddr`, `SocketAddrV4`, and `SocketAddrV6`.

# Potential causes

`AddrParseError` may be thrown because the provided string does not parse as the given type, often because it includes information only handled by a different address type.

    use std::net::IpAddr;
    let _foo: IpAddr = "127.0.0.1:8080".parse().expect("Cannot handle the socket port");

Run

`IpAddr` doesn't handle the port. Use `SocketAddr` instead.

    use std::net::SocketAddr;

    // No problem, the `panic!` message has disappeared.
    let _foo: SocketAddr = "127.0.0.1:8080".parse().expect("unreachable panic");

Run
