void

resolveFiber

(

Connection conn

const string address

const ushort port

const Flag!"useIPv6" useIPv6

const Flag!"abort"* abort

)

Parameters

conn Connection: The current Connection.
address string: String address to look up.
port ushort: Remote port build into the Address.
useIPv6 Flag!"useIPv6": Whether to include resolved IPv6 addresses or not.
abort Flag!"abort"*: Pointer to the "abort" flag, which -- if set -- should make the function return and the Fiber terminate.

Examples

import std.concurrency : Generator;

Connection conn;
conn.reset();

auto resolver = new Generator!ResolveAttempt(() =>
    resolveFiber(
        conn,
        "irc.libera.chat",
        6667,
        false,
        abort));

resolveloop:
foreach (const attempt; resolver)
{
    // attempt is a yielded `ResolveAttempt`

    with (ResolveAttempt.State)
    final switch (attempt.state)
    {
    case preresolve:
        assert(0, "shouldn't happen");

    case success:
        // Address was resolved, the passed `conn` was modified
        break resolveloop;

    case exception:
        // Recoverable
        dealWithException(attempt.error);
        break;

    case failure:
        // Resolution failed without errors
        failGracefully(attempt.error);
        break;

    case error:
        // Unrecoverable
        dealWithError(attempt.error);
        return;
    }
}

// Address resolved
