Struct AddressHints 

pub struct AddressHints {
    pub domain: Option<SocketDomain>,
    pub socket_type: Option<SocketType>,
    pub protocol: Option<SocketProtocol>,
    pub passive: bool,
    pub numeric_host: bool,
    pub address_configured: bool,
}

Typed hints passed to the resolver. Defaults request either IP family, any socket type/protocol, and no flags.

Fields

domain: Option<SocketDomain>

Restrict results to one IP family; None accepts either.

socket_type: Option<SocketType>

Restrict results to one socket type; None accepts any.

protocol: Option<SocketProtocol>

Restrict results to one protocol; None accepts any.

passive: bool

With no hostname, request wildcard addresses suitable for binding; otherwise this flag has no effect. Without this flag, an absent hostname selects loopback addresses.

numeric_host: bool

Require a numeric hostname, preventing hostname lookup. Literal syntax, including IPv6 scope identifiers, follows the backend.

address_configured: bool

Ask the resolver to return families configured on the local system (AI_ADDRCONFIG). This is opt-in; loopback addresses do not establish a configured family on native backends.
