DNS lookup operations used by propagation and zone discovery.

The default solver implementation uses crate::dnsutil and the system resolver. Callers that already have a DNS client, and tests that must not touch the network, can inject an implementation with Dns01Solver::with_resolver. An empty resolvers slice means the implementation should use its authoritative-name-server path; non-empty entries are explicit IP addresses (port 53) or IP socket addresses with an explicit port, such as 127.0.0.1:5300 or [::1]:5300.

Required Methods

fn find_zone<'life0, 'life1, 'async_trait>( &'life0 self, fqdn: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Find the closest SOA apex for fqdn.

fn txt_contains<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, name: &'life1 str, value: &'life2 str, resolvers: &'life3 [String], ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Check whether name contains value.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
