Enum ns_router::AutoName

pub enum AutoName<'a> {
    Auto(&'a str),
    HostPort(&'a str, u16),
    HostDefaultPort(&'a str),
    Service(&'a str),
    IpAddr(IpAddr),
    SocketAddr(SocketAddr),
}

A name type that can be read from config

The core idea of AutoName is that for service with default port 80 (HTTP) we treat names the following way:

• example.org → A record example.org, port 80
• example.org:8080 → A record example.org, port 8080
• _service._proto.example.org → SRV record, and port from the record
• 127.0.0.1 → IP used directly, port 80
• 127.0.0.1:8080 → IP/port used directly
• 2001:db8::2:1 → IPv6 address (note: no brackets)
• [2001:db8::2:1]:1235 → IPv6 address and port (note: square brackets)

This works by wrapping the string read from configuration file into AutoName::Auto and using it in Router. You might override things via configuration specific things, for example in yaml you might want to write:

addresses:
- !Srv myservice.query.consul

... And convert it into Service("myservice.query.consul") which will be resolved using SRV record (or similar mechanism) instead of using hostname (i.e. standard expects using _service._proto prefix but does not requires that).

Variants

Auto(&'a str)

Auto-determine how to treat the name

HostPort(&'a str, u16)

Resolve host and attach specified port

HostDefaultPort(&'a str)

Resolve host and attach default port to it

Service(&'a str)

Use service name and port resolved using SRV record or similar

IpAddr(IpAddr)

A bare IP used directly as a host

SocketAddr(SocketAddr)

A bare socket address used directly as a service address
