Struct Node 

pub struct Node { /* private fields */ }

Represents a single server instance (node) in the Product OS cluster.

Each node has a unique identifier, machine ID, URI, and tracks its own capabilities, services, features, and failure count.

Implementations

impl Node

pub fn new(config: &CommandControl, certificates: Certificates) -> Self

Creates a new Node instance with the given configuration and certificates.

Generates a unique UUID, retrieves the machine ID, and initialises the node with the configured URL address.

Panics

Panics if the machine UID cannot be retrieved or if the configured URL address is not a valid URI.

pub fn default(config: &CommandControl, certificates: Certificates) -> Self

👎Deprecated since 0.0.28:

Renamed to Node::new() to follow Rust conventions

Creates a new Node instance with the given configuration and certificates.

pub fn get_identifier(&self) -> String

Returns the unique identifier for this node as a string.

pub fn get_protocol(&self) -> String

👎Deprecated since 0.0.28:

Use try_get_protocol() to avoid potential panics

Returns the URI protocol scheme (e.g., “https”) for this node.

Returns an empty string if the URI has no scheme.

pub fn try_get_protocol(&self) -> Option<String>

Returns the URI protocol scheme (e.g., “https”) for this node, or None if the URI is invalid.

pub fn get_address(&self) -> Uri

👎Deprecated since 0.0.28:

Use try_get_address() to avoid potential panics

Returns the parsed URI address for this node.

Panics

Panics if the stored URI string is not valid. This should not happen if the node was constructed via Node::new().

pub fn try_get_address(&self) -> Option<Uri>

Returns the parsed URI address for this node, or None if the URI is invalid.

pub fn get_process_id(&self) -> u32

Returns the OS process ID of this node.

pub fn get_certificate(&self) -> Vec<u8>

Returns a copy of the certificate bytes for this node.

pub fn get_failures(&self) -> u8

Returns the current failure count for this node.

pub fn get_features(&self) -> &Features

Returns a reference to this node’s registered features.

pub fn get_services(&self) -> &Services

Returns a reference to this node’s registered services.

pub fn match_node(&self, selector: &str, search_value: &str) -> bool

Tests whether this node matches a single selector/value pair.

Supported selectors:

• "feature" - checks if the node has the named feature
• "capability" - checks if the node has the named capability (empty capabilities match nothing)
• "service.kind" - checks if the node has a service of the given kind
• "service.enabled" - checks if all services match the enabled state
• "service.active" - checks if all services match the active state

pub fn match_node_query(&self, query: &BTreeMap<&str, &str>) -> bool

Tests whether this node matches all selector/value pairs in the query.

Returns true only if every entry in the query matches. An empty query always matches.

pub fn get_created_at(&self) -> DateTime<Utc>

Returns the timestamp when this node was created.

pub fn get_last_updated_at(&self) -> DateTime<Utc>

Returns the timestamp when this node was last updated.
