u16
type alias
rust
pub type Port = u16;
The select_free_port
requires a structure passed in
rust
pub struct Selector {
// Check whether the port is available on TCP.
// The default value is true.
pub check_tcp: bool,
// Check whether the port is available on UDP.
// The default value is true.
pub check_udp: bool,
// Set the range of generated ports, default (0, 65525)
pub port_range: (u16, u16),
// Maximum number of random times. Default value: 100
// If no available port number is found within the maximum random number of loops, None is returned
pub max_random_times: u16,
}
is_free_tcp
Check whether the port is not used on TCP
rust
pub fn is_free_udp(port: Port) -> bool
is_free_udp
Check whether the port is not used on UDP
rust
pub fn is_free_udp(port: Port) -> bool
is_free
Check whether the port is not used on TCP and UDP
rust
pub fn is_free(port: Port) -> bool
random_free_tcp_port
The system randomly assigns available TCP ports
rust
pub fn random_free_tcp_port() -> Option<Port>
random_free_udp_port
The system randomly assigns available UDP ports
rust
pub fn random_free_udp_port() -> Option<Port>
random_free_port
The system randomly assigns available TCP and UDP ports
rust
pub fn random_free_port() -> Option<Port>
select_from_given_port
Check from given_port
and return the first available port
Return if given_port
is available; Otherwise given_port += given_port
until the port is available
rust
pub fn select_from_given_port(given_port: Port) -> Option<Port>
select_free_port
Gets a matching port based on the Selector
parameter constraint
rust
pub fn select_free_port(selector: Selector) -> Option<Port>
