Struct ViewIntent 

pub struct ViewIntent {
    pub view_id: String,
    pub scope: String,
    pub role_key: String,
    pub request_id: String,
}

A ring view intent injected into FU.Data for mediated view projection.

ViewIntent is to views what RingCommand is to commands: the input envelope that starts a ring cycle. A view cycle produces projected output in SU (shape governed by C3’s route and the organ’s AROUND extension).

The envelope is shorter than RingCommand because views have no free-form parameters at this layer — everything needed to select data comes from view_id (resolved via the ViewRegistry in soma-interface) and GUARD’s scope evaluation over scope + role_key.

Fields

view_id: String

View identifier — e.g. organ.mirror, term.fu.data.tree, ext.git.commit.viewer. Resolves through ViewRegistry.

scope: String

GUARD scope the requestor is asking under. CU uses this to decide which projection slice is visible.

role_key: String

Role key of the requestor (application-defined label).

CU uses this for authorization scope evaluation. Injected into the Tree as view.requestor_role by convention.

request_id: String

Request correlation ID for tracing. Generated by the web layer, carried through the cycle.

Implementations

impl ViewIntent

pub fn new( view_id: impl Into<String>, scope: impl Into<String>, role_key: impl Into<String>, request_id: impl Into<String>, ) -> Self

Create a new view intent.

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

Inject this view intent into a Tree as view.* entries.

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

Extract a view intent from a Tree’s view.* entries.

Returns None if view.id is absent (not a view cycle).

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

Check if a Tree contains a view intent (has view.id).

Trait Implementations

impl Clone for ViewIntent

fn clone(&self) -> ViewIntent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewIntent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ViewIntent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ViewIntent

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
