Enum PortPair 

pub enum PortPair {
    Distinct {
        host: u16,
        guest: u16,
    },
    Same(u16),
}

Represents a port mapping between host and guest systems, following Docker’s port mapping convention.

Format

The port pair can be specified in two formats:

• host:guest - Maps the host port to a different guest port (e.g., “8080:80”)
• port or port:port - Maps the same port number on both host and guest (e.g., “8080” or “8080:8080”)

Examples

Creating port pairs:

use microsandbox_core::config::PortPair;

// Same port on host and guest (8080:8080)
let same_port = PortPair::with_same(8080);

// Different ports (host 8080 maps to guest 80)
let distinct_ports = PortPair::with_distinct(8080, 80);

// Parse from string
let from_str = "8080:80".parse::<PortPair>().unwrap();
assert_eq!(from_str, distinct_ports);

Variants

Distinct

The guest port and the host port are distinct.

Fields

host: u16

The host port.

guest: u16

The guest port.

Same(u16)

The guest port and the host port are the same.

Implementations

impl PortPair

pub fn with_same(port: u16) -> Self

Creates a new PortPair with the same guest and host port.

pub fn with_distinct(host: u16, guest: u16) -> Self

Creates a new PortPair with distinct guest and host ports.

pub fn get_host(&self) -> u16

Returns the host port.

pub fn get_guest(&self) -> u16

Returns the guest port.

Trait Implementations

impl Clone for PortPair

fn clone(&self) -> PortPair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortPair

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PortPair

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PortPair

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

Formats the port pair following the format “host:guest”.

impl FromStr for PortPair

type Err = MicrosandboxError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for PortPair

fn eq(&self, other: &PortPair) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PortPair

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
