Struct c_ares::NSResults

pub struct NSResults { /* fields omitted */ }

The result of a successful NS lookup.

Methods

impl NSResults

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

Obtain an NSResults from the response to an NS lookup.

pub fn hostname(&self) -> &CStr

Returns the hostname from this NSResults.

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.
