Struct Pool

pub struct Pool { /* private fields */ }

A representation of a set of network resources that may be accessed.

This is presently a very simple concept, though it could grow in sophistication in the future.

Pool implements Clone, which creates new independent entities that carry the full authority of the originals. This means that in a borrow of a Pool, the scope of the authority is not necessarily limited to the scope of the borrow.

Similarly, the cap_net_ext::PoolExt class allows creating “binder” and “connecter” objects which represent capabilities to bind and connect to addresses.

Implementations

impl Pool

pub fn new() -> Self

Construct a new empty pool.

pub fn insert<A: ToSocketAddrs>( &mut self, addrs: A, ambient_authority: AmbientAuthority, ) -> Result<()>

Add addresses to the pool.

Ambient Authority

This function allows ambient access to any IP address.

pub fn insert_socket_addr( &mut self, addr: SocketAddr, ambient_authority: AmbientAuthority, )

Add a specific net::SocketAddr to the pool.

Ambient Authority

This function allows ambient access to any IP address.

pub fn insert_ip_net_port_any( &mut self, ip_net: IpNet, ambient_authority: AmbientAuthority, )

Add a range of network addresses, accepting any port, to the pool.

Ambient Authority

This function allows ambient access to any IP address.

pub fn insert_ip_net_port_range( &mut self, ip_net: IpNet, ports_start: u16, ports_end: Option<u16>, ambient_authority: AmbientAuthority, )

Add a range of network addresses, accepting a range of ports, to the pool.

This grants access to the port range starting at ports_start and, if ports_end is provided, ending before ports_end.

Ambient Authority

This function allows ambient access to any IP address.

pub fn insert_ip_net( &mut self, ip_net: IpNet, port: u16, ambient_authority: AmbientAuthority, )

Add a range of network addresses with a specific port to the pool.

Ambient Authority

This function allows ambient access to any IP address.

pub fn check_addr(&self, addr: &SocketAddr) -> Result<()>

Check whether the given address is within the pool.

Trait Implementations

impl Clone for Pool

fn clone(&self) -> Pool

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Pool

fn default() -> Pool

Returns the “default value” for a type.
