Spec for starting a query.

Implementations§

Source§

impl QuerySpec

Source

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

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

Build a new spec for an mDNS query.

Source

pub fn qname(&self) -> &Name

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

The query name.

Source

pub const fn qtype(&self) -> ResourceType

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

The query resource type.

Source

pub const fn qclass(&self) -> ResourceClass

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

The query class.

Source

pub const fn unicast_response(&self) -> bool

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

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

Source

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

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

The absolute timeout for the query, if set.

Source

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

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

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) -> QuerySpec

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

Override the query class.

Source

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

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

Request unicast responses (RFC 6762 §5.4).

Source

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

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

Set an absolute timeout for the query.

Source

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

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

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
