Struct System

pub struct System {
    pub addr_info_hints: Option<AddrInfoHints>,
    pub service: Option<String>,
}

System encapsulates logic to perform the name resolution in the background using system resolution mechanisms.

Uses dns_lookup::getaddrinfo in a tokio::task::spawn_blocking to perform the resolution.

Fields

addr_info_hints: Option<AddrInfoHints>

The hints to give the the system resolver when performing the resolution.

Passing None is not equivalent to passing Some value filled with zeroes, as underlying systems typically have some non-trivial defaults when hint is omitted.

service: Option<String>

The name of the service to resolve. If set to None, the network address of the node is resolved. If set to Some, the the requested service address is resolved. This can be either a descriptive name or a numeric representation suitable for use with the address family or families. If the specified address family is AF_INET, AF_INET6, or AF_UNSPEC, the service can be specified as a string specifying a decimal port number.

Implementations

impl System

pub fn resolver(self) -> Resolver
