Struct c_ares::PTRResults

source ·

pub struct PTRResults { /* private fields */ }

Expand description

The result of a successful PTR lookup.

Implementations

source

impl PTRResults

source

pub fn parse_from(data: &[u8]) -> Result<PTRResults>

Obtain a PTRResults from the response to a PTR lookup.

source

pub fn hostname(&self) -> &CStr

Returns the hostname from this PTRResults.

In practice this is very likely to be a valid UTF-8 string, but the underlying c-ares library does not guarantee this - so we leave it to users to decide whether they prefer a fallible conversion, a lossy conversion, or something else altogether.

source

pub fn aliases(&self) -> HostAliasResultsIter<'_> ⓘ

Returns an iterator over the host aliases in this PTRResults.
