Struct BTreeFactStore 

pub struct BTreeFactStore { /* private fields */ }

In-memory FactStore backed by BTreeMaps with a triple index; the kernel default.

Implementations

impl BTreeFactStore

pub fn new() -> Self

Creates an empty store.

pub fn len(&self) -> usize

Returns the number of stored claims.

pub fn is_empty(&self) -> bool

Returns whether the store holds no claims.

pub fn get(&self, id: &ContentId) -> Option<&Claim>

Returns the stored claim with content id id, if present.

pub fn remove(&mut self, id: &ContentId) -> Option<Claim>

Removes the claim with content id id, updating every query index.

pub fn insert_boot_claims(&mut self, data: &mut BTreeDatumStore)

Seeds the fixed core boot claims (the kernel class kind facts) into this store and their datums into data.

Trait Implementations

impl Clone for BTreeFactStore

fn clone(&self) -> BTreeFactStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BTreeFactStore

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

Formats the value using the given formatter.

impl Default for BTreeFactStore

fn default() -> BTreeFactStore

Returns the “default value” for a type.

impl FactStore for BTreeFactStore

fn insert_authorized( &mut self, capabilities: &CapabilitySet, data: &mut dyn DatumStore, claim: Claim, ) -> Result<Ref>

Inserts claim after checking the caller’s capabilities, returning its content Ref; private claims require the fact-private capability.

fn query_authorized(&self, cx: &Cx, pattern: ClaimPattern) -> Result<Vec<Claim>>

Returns the claims matching pattern that are visible under cx’s capabilities.
