Struct async_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");

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");

impl Eq for AddrParseError

impl Error for AddrParseError

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<AddrParseError> for AddrParseError
