DNS recursive lookup utility

Fields

domain: DomainName

Domain name to resolve

qtype: QueryType

Query type to resolve

authoritative_only: bool

Only answer queries for which this configuration is authoritative: do not perform recursive or forwarding resolution

protocol_mode: ProtocolMode

How to choose between connecting to upstream nameservers over IPv4 or IPv6 when acting as a recursive resolver: one of ‘only-v4’, ‘prefer-v4’, ‘prefer-v6’, ‘only-v6’

upstream_dns_port: u16

Which port to query upstream nameservers over when acting as a recursive resolver

forward_address: Option<SocketAddr>

Act as a forwarding resolver, not a recursive resolver: forward queries which can’t be answered from local state to this nameserver (in ip:port form)

hosts_file: Vec<PathBuf>

Path to a hosts file, can be specified more than once

hosts_dir: Vec<PathBuf>

Path to a directory to read hosts files from, can be specified more than once

zone_file: Vec<PathBuf>

Path to a zone file, can be specified more than once

zones_dir: Vec<PathBuf>

Path to a directory to read zone files from, can be specified more than once

Trait Implementations

impl Args for Args

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl CommandFactory for Args

fn command<'b>() -> Command

Build a [Command] that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a [Command] that can update self.

impl FromArgMatches for Args

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for Args

fn parse() -> Self

Parse from std::env::args_os(), [exit][Error::exit] on error.

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, [exit][Error::exit] on error.

fn try_parse_from<I, T>(itr: I) -> Result<Self, Error>

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Parse from iterator, return Err on error.

fn update_from<I, T>(&mut self, itr: I)

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Update from iterator, [exit][Error::exit] on error.

fn try_update_from<I, T>(&mut self, itr: I) -> Result<(), Error>

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,

Update from iterator, return Err on error.
