Struct Catalogue 

pub struct Catalogue { /* private fields */ }

The validated catalogue and every index derived from it. Immutable: built once from an index and a registry, read many times.

Implementations

impl Catalogue

pub fn build(index: &Index, registry: &CapabilityRegistry) -> Self

Build the catalogue from an index and the registry its capability references resolve against. Deterministic: the same objects produce the same value, and no derivation reads a clock or the filesystem.

impl Catalogue

pub fn all(&self) -> &[Moment]

Every moment the catalogue holds, in presentation order, whatever its status.

pub fn audiences(&self) -> &[Audience]

Every audience, in presentation order.

pub fn areas(&self) -> &[Area]

Every area, in presentation order.

pub fn moment(&self, id: &str) -> Option<&Moment>

One moment by id.

pub fn audience(&self, id: &str) -> Option<&Audience>

One audience by id.

pub fn area(&self, id: &str) -> Option<&Area>

One area by id.

pub fn findings(&self) -> &[Finding]

Every finding: unresolved references, duplicate identities, and records that do not meet the floor their status promises.

pub fn errors(&self) -> usize

How many findings are errors.

pub fn fingerprint(&self) -> &str

The hash of the catalogue’s own sources.

pub fn responsibilities(&self, id: &str) -> &[String]

The responsibilities a moment touches, derived from the claims it names.

pub fn backlinks(&self, id: &str) -> &[String]

The moments that name this one in their related. Never authored.

pub fn naming(&self, field: &str, value: &str) -> Vec<&Moment>

The moments that name this thing, whatever kind of thing it is. This is the one reverse index every “the moments this answers” list is read from.

pub fn signal_owner(&self, signal: &str) -> Option<&Moment>

The moment a signal belongs to.

pub fn select(&self, q: &Query) -> Vec<&Moment>

The moments a query selects, in presentation order.

impl Catalogue

pub fn facets(&self) -> Facets

The facets, counted over the public moments. A value with no public moment is not offered: a filter that answers nothing is not a filter.

impl Catalogue

pub fn diagnose(&self, selected: &[String]) -> Diagnosis

Diagnose a selection. Each name may be a signal id or a moment id; a signal resolves to the moment that owns it, so a reader ticking symptoms and a script naming moments reach the same answer.

Trait Implementations

impl Clone for Catalogue

fn clone(&self) -> Catalogue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Catalogue

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

Formats the value using the given formatter.

impl Default for Catalogue

fn default() -> Catalogue

Returns the “default value” for a type.
