Struct c_ares::HostResults

pub struct HostResults<'a> { /* fields omitted */ }

The result of a successful host lookup.

Methods

impl<'a> HostResults<'a>

pub fn hostname(self) -> &'a CStr

Returns the hostname from this HostResults.

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.
