Struct tor_netdoc::types::policy::PortRange

pub struct PortRange {
    pub lo: u16,
    pub hi: u16,
}

A PortRange is a set of consecutively numbered TCP or UDP ports.

Example

use tor_netdoc::types::policy::PortRange;

let r: PortRange = "22-8000".parse().unwrap();
assert!(r.contains(128));
assert!(r.contains(22));
assert!(r.contains(8000));

assert!(! r.contains(21));
assert!(! r.contains(8001));

Fields

lo: u16

The first port in this range.

hi: u16

The last port in this range.

Implementations

impl PortRange

pub fn new_all() -> Self

Create a port range containing all ports.

pub fn new(lo: u16, hi: u16) -> Option<Self>

Create a new PortRange.

The Portrange contains all ports between lo and hi inclusive.

Returns None if lo is greater than hi, or if either is zero.

pub fn contains(&self, port: u16) -> bool

Return true if a port is in this range.

pub fn is_all(&self) -> bool

Return true if this range contains all ports.

Trait Implementations

impl Clone for PortRange

fn clone(&self) -> PortRange

Returns a copy of the value.

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

impl Debug for PortRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PortRange

A PortRange is displayed as a number if it contains a single port, and as a start point and end point separated by a dash if it contains more than one port.

fn fmt(&self, f: &mut Formatter<'_>) -> Result
