Struct mtop_client::dns::DnsClientConfig

pub struct DnsClientConfig {
    pub nameservers: Vec<SocketAddr>,
    pub timeout: Duration,
    pub attempts: u8,
    pub rotate: bool,
    pub pool_max_idle: u64,
}

Configuration for creating a new DnsClient instance.

Fields

nameservers: Vec<SocketAddr>

One or more DNS nameservers to use for resolution. These servers will be tried in order for each resolution unless rotate is set.

timeout: Duration

Timeout for each resolution. This timeout is applied to each attempt and so a single call to DnsClient::resolve may take longer based on the value of attempts.

attempts: u8

Number of attempts to make performing a resolution for a single name. Note that any response from a DNS server counts as “success”. Only timeout or network errors will trigger retries.

rotate: bool

If true, nameservers will be round-robin load balanced for each resolution. If false the nameservers are tried in-order for each resolution.

pool_max_idle: u64

Max number of open sockets or connections to each nameserver. Default is to keep one open socket or connection per nameserver. Set to 0 to disable this behavior.
