Struct BackendServerConfig 

#[non_exhaustive]
pub struct BackendServerConfig {
    pub host: Option<String>,
    pub port: Option<u16>,
    pub admin_name: Option<Arc<str>>,
    pub tango_host: Option<(Arc<str>, u16)>,
}

How a backend serves, see Backend::serve, whatever is not given being left to the backend, which is what the default configuration is.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

host: Option<String>

The host to listen at, an address or a name of this machine, every one of its interfaces if none is given.

port: Option<u16>

The port to listen at, one the system picks if none is given, which is what a Tango device server does: its clients find it through the database, where it is exported. A fixed port is what a server without a database needs, its clients having nothing else to find it by.

admin_name: Option<Arc<str>>

The name of the admin device of the server being served, dserver/exe/inst, which names the event channel of the server: a backend not given one publishes no event.

tango_host: Option<(Arc<str>, u16)>

The host and port of the database the server is registered in, which prefixes the names of its events. A server without a database prefixes them with its own host and port instead, marking them as such.

Implementations

impl BackendServerConfig

pub fn new() -> Self

Everything left to the backend.

pub fn with_host(self, host: &str) -> Self

Listen at that host, see Self::host.

pub fn with_port(self, port: u16) -> Self

pub fn with_admin_name(self, admin_name: impl Into<Arc<str>>) -> Self

Serve the server of that admin device, see Self::admin_name.

pub fn with_tango_host(self, host: impl Into<Arc<str>>, port: u16) -> Self

Serve a server registered in the database at that host and port, see Self::tango_host.
