Struct Node

pub struct Node<I, A> { /* private fields */ }

Node is consist of id and address, which can be used as a identifier in a distributed system.

Implementations

impl<I, A> Node<I, A>

pub const fn new(id: I, address: A) -> Node<I, A>

pub const fn id(&self) -> &I

Returns the id of the node.

pub const fn address(&self) -> &A

Returns the address of the node.

pub fn set_address(&mut self, address: A) -> &mut Node<I, A>

Set the address of the node.

pub fn set_id(&mut self, id: I) -> &mut Node<I, A>

Set the id of the node.

pub fn with_address(self, address: A) -> Node<I, A>

Set the address of the node. (Builder pattern)

pub fn with_id(self, id: I) -> Node<I, A>

Set the id of the node. (Builder pattern)

pub fn into_components(self) -> (I, A)

Consumes the node and returns the id and address of the node.

pub fn map_address<U>(self, f: impl FnOnce(A) -> U) -> Node<I, U>

Maps an Node<I, A> to Node<I, U> by applying a function to the current node.

Example

use nodecraft::Node;

let node = Node::new("test", 100u64);
let node = node.map_address(|address| address.to_string());
assert_eq!(node.address(), "100");

pub fn map_id<U>(self, f: impl FnOnce(I) -> U) -> Node<U, A>

Maps an Node<I, A> to Node<U, A> by applying a function to the current node.

Example

use nodecraft::Node;

let node = Node::new(1u64, 100u64);
let node = node.map_id(|id| id.to_string());
assert_eq!(node.id(), "1");

pub fn map<U, V>(self, f: impl FnOnce(I, A) -> (U, V)) -> Node<U, V>

Maps an Node<I, A> to Node<U, V> by applying a function to the current node.

Example

use nodecraft::Node;

let node = Node::new(1u64, 100u64);

let node = node.map(|id, address| (id.to_string(), address.to_string()));

assert_eq!(node.id(), "1");
assert_eq!(node.address(), "100");
