Available on crate features alloc or heapless or no-atomic or std only.
Expand description

Spec for starting a query.

Implementations§

Source§

impl QuerySpec

Source

pub fn new(qname: Name, qtype: ResourceType) -> Self

Build a new spec for an mDNS query.

Source

pub fn qname(&self) -> &Name

The query name.

Source

pub const fn qtype(&self) -> ResourceType

The query resource type.

Source

pub const fn qclass(&self) -> ResourceClass

The query class.

Source

pub const fn unicast_response(&self) -> bool

Whether to request unicast responses (RFC 6762 §5.4).

Source

pub const fn timeout(&self) -> Option<Duration>

The absolute timeout for the query, if set.

Source

pub const fn max_answers(&self) -> Option<usize>

Maximum number of collected answers, if explicitly overridden.

When None the Query state machine uses its built-in default (256).

Source

pub const fn with_qclass(self, v: ResourceClass) -> Self

Override the query class.

Source

pub const fn with_unicast_response(self, v: bool) -> Self

Request unicast responses (RFC 6762 §5.4).

Source

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

Set an absolute timeout for the query.

Source

pub const fn with_max_answers(self, max: usize) -> Self

Override the maximum number of collected answers for this query.

When the pool reaches max, the oldest entry (FIFO) is evicted to make room. Setting max to 0 disables answer collection entirely.

impl Eq for QuerySpec

Source§

impl PartialEq for QuerySpec

Source§

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

Tests for self and other values to be equal, and is used by ==.
1.0.0 (const: unstable) · Source§

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

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