Struct RingCommand 

pub struct RingCommand {
    pub command_type: String,
    pub payload: String,
    pub actor: String,
    pub role_key: String,
    pub request_id: String,
}

A ring command injected into FU.Data for mediated processing.

The command envelope carries the operation type, a JSON payload, the requesting actor identity, their role key, and a correlation ID. All fields serialize to command.* Tree entries via RingCommand::inject_into.

Fields

command_type: String

Command type identifier (e.g. user.create).

payload: String

JSON-serialized command parameters.

actor: String

Identity of the actor making the request (application-defined label).

CU uses this for authorization decisions. Injected into the Tree as command.admin by convention; applications may interpret this field according to their own identity model.

role_key: String

Role key of the requesting actor (application-defined label).

CU evaluates permissions based on this role key. Injected into the Tree as command.role by convention.

request_id: String

Request correlation ID for tracing.

Generated by the web layer, carried through all 6 units, returned in the result for response correlation.

Implementations

impl RingCommand

pub fn new( command_type: impl Into<String>, payload: impl Into<String>, actor: impl Into<String>, role_key: impl Into<String>, request_id: impl Into<String>, ) -> Self

Create a new ring command.

pub fn inject_into(&self, tree: &mut Tree)

Inject this command into a Tree as command.* entries.

pub fn extract_from(tree: &Tree) -> Option<Self>

Extract a command from a Tree’s command.* entries.

Returns None if command.type is absent (not a command cycle).

pub fn is_command(tree: &Tree) -> bool

Check if a Tree contains a command (has command.type).

Trait Implementations

impl Clone for RingCommand

fn clone(&self) -> RingCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RingCommand

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RingCommand

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RingCommand

fn eq(&self, other: &RingCommand) -> 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 RingCommand

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
