Expand description

The DNS lookups this crate needs.

Abstracted so tests can drive every branch — no PTR, a mismatched forward record, a timeout — from canned data instead of the network.

Required Methods§

Source

fn reverse<'life0, 'async_trait>( &'life0 self, ip: IpAddr, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, String>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

PTR names for ip, or an error describing why the lookup failed.

Source

fn forward<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<IpAddr>, String>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

A/AAAA addresses for name.

Source

fn txt<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, String>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

TXT records for name.

A record’s character-strings are concatenated (RFC 1035 §3.3.14): a value over 255 octets arrives split. A dns-01 value never is, but a provider padding the record would otherwise never match.

Dyn Compatibility§

This trait is dyn compatible.

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