Resolved

tor_cell::relaycell::msg

Struct Resolved 

Source 
pub struct Resolved { /* private fields */ }
Expand description

A Resolved message is a successful reply to a Resolve message.

The Resolved message contains a list of zero or more addresses, and their associated times-to-live in seconds.

Implementations§

Source§

impl Resolved

Source

pub fn new_empty() -> Self

Return a new empty Resolved object with no answers.

Source

pub fn new_err(transient: bool, ttl: u32) -> Self

Return a new Resolved object reporting a name lookup error.

TODO: Is getting no answer an error; or it is represented by a list of no answers?

Source

pub fn add_answer(&mut self, answer: ResolvedVal, ttl: u32)

Add a single answer to this Resolved message

Source

pub fn into_answers(self) -> Vec<(ResolvedVal, u32)>

Consume this Resolved message, returning a vector of the answers and TTL values that it contains.

Note that actually relying on these TTL values can be dangerous in practice, since the relay that sent the cell could be lying in order to cause more lookups, or to get a false answer cached for longer.
