Required Methods§

Source

fn resolve_addresses<T>( accessor: &Accessor<T, Self>, name: String, ) -> impl Future<Output = Result<Result<Vec<IpAddress>, ErrorCode>>> + Send

Resolve an internet host name to a list of IP addresses.

Unicode domain names are automatically converted to ASCII using IDNA encoding. If the input is an IP address string, the address is parsed and returned as-is without making any external requests.

See the wasi-socket proposal README.md for a comparison with getaddrinfo.

The results are returned in connection order preference.

This function never succeeds with 0 results. It either fails or succeeds with at least one address. Additionally, this function never returns IPv4-mapped IPv6 addresses.

The returned future will resolve to an error code in case of failure. It will resolve to success once the returned stream is exhausted.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
