Struct Interface 

pub struct Interface {
    pub name: String,
    pub auto: bool,
    pub allow: Vec<String>,
    pub family: Option<Family>,
    pub method: Option<String>,
    pub options: Vec<(String, String)>,
    pub mapping: Option<Mapping>,
}

Represents a network interface configuration in an interfaces(5) file.

The Interface struct encapsulates all the configuration details for a network interface, including its name, whether it starts automatically, allowed hotplug options, address family, method of configuration, and additional options.

To construct an Interface, it is recommended to use the InterfaceBuilder via the Interface::builder method for a more ergonomic and fluent API.

Examples

Creating a new Interface using the builder pattern:

use interface_rs::interface::{Interface, Family};

let iface = Interface::builder("eth0")
    .with_auto(true)
    .with_allow("hotplug")
    .with_family(Family::Inet)
    .with_method("dhcp")
    .with_option("mtu", "1500")
    .build();

Fields

name: String

The name of the interface (e.g., "eth0").

auto: bool

Indicates if the interface is set to start automatically.

allow: Vec<String>

A list of allow-* directives associated with the interface.

family: Option<Family>

The address family (e.g., inet).

method: Option<String>

The method of configuration (e.g., "static", "dhcp").

options: Vec<(String, String)>

A list of options specified under the iface stanza.

mapping: Option<Mapping>

Optional mapping configuration for the interface.

Implementations

impl Interface

pub fn builder(name: impl Into<String>) -> InterfaceBuilder

Creates a new InterfaceBuilder for constructing an Interface.

Arguments

• name - The name of the interface (e.g., "eth0").

Examples

use interface_rs::interface::Interface;

let builder = Interface::builder("eth0");

pub fn edit(&self) -> InterfaceBuilder

Creates a new InterfaceBuilder initialized with this Interface’s data.

This method allows you to modify an existing Interface using the builder pattern.

Examples

use interface_rs::interface::{Interface, Family};

let iface = Interface::builder("eth0")
    .with_auto(true)
    .with_family(Family::Inet)
    .with_method("dhcp")
    .build();

// Modify the existing interface
let modified_iface = iface.edit()
    .with_method("static")
    .with_option("address", "192.168.1.50")
    .build();
