Struct QueryParameters 

pub struct QueryParameters {
    pub query_type: QueryType,
    pub base_repeat_interval: Option<Duration>,
    pub max_repeat_interval: Option<Duration>,
    pub exponential_backoff: bool,
    pub timeout_after: Option<Duration>,
}

Controls how to perform the query. You will typically use one of the associated constants DISCOVERY, SERVICE_LOOKUP, HOST_LOOKUP

Fields

query_type: QueryType

base_repeat_interval: Option<Duration>

If specified, the query will be re-issued after this duration

max_repeat_interval: Option<Duration>

The maximum interval between retries

exponential_backoff: bool

If true, repeat interval will be doubled on each iteration until it reaches the max_repeat_interval. If false, it will increment by base_repeat_interval on each iteration until it reaches the max_repeat_interval.

timeout_after: Option<Duration>

If set, specifies the upper bound on total time spent processing the request. Otherwise, the request will keep going forever, subject to the repeat interval.

Implementations

impl QueryParameters

pub const DISCOVERY: QueryParameters

Parameters suitable for performing long-running discovery. Repeatedly performs a PTR lookup with exponential backoff ranging from 2 seconds up to 5 minutes.

pub const SERVICE_LOOKUP: QueryParameters

Parameters suitable for performing short-lived discovery. Repeatedly performs a PTR lookup with exponential backoff ranging from 2 seconds up to 5 minutes.

pub const HOST_LOOKUP: QueryParameters

Parameters suitable for resolving a single host. Performs an A lookup with exponential backoff ranging from 1 second. The overall lookup will timeout after 1 minutes.

pub fn with_timeout(self, timeout: Duration) -> Self

Trait Implementations

impl Clone for QueryParameters

fn clone(&self) -> QueryParameters

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryParameters

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for QueryParameters

fn eq(&self, other: &QueryParameters) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
