Struct RootAccessTrie

pub struct RootAccessTrie { /* private fields */ }

Available on crate feature entity-manifest only.

A RootAccessTrie is a trie describing a set of data paths to retrieve. Each edge in the trie is either a record or entity dereference.

If an entity or record field does not exist in the backing store, it is safe to stop loading data at that point.

T represents an optional type annotation on each node in the AccessTrie.

This feature is experimental. For more information see https://github.com/cedar-policy/rfcs/blob/main/README.md#experimental-features

Implementations

impl RootAccessTrie

pub fn trie(&self) -> &HashMap<EntityRoot, AccessTrie>

Get the trie as a hash map from EntityRoot to sub-AccessTries.

impl RootAccessTrie

pub fn new() -> RootAccessTrie

Create an empty RootAccessTrie that requests nothing.

impl RootAccessTrie

pub fn union(self, other: &RootAccessTrie) -> RootAccessTrie

Union two RootAccessTries together. The new trie requests the data from both of the original.

pub fn union_mut(&mut self, other: &RootAccessTrie)

Like RootAccessTrie::union, but modifies the current trie.

Trait Implementations

impl Clone for RootAccessTrie

fn clone(&self) -> RootAccessTrie

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RootAccessTrie

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

Formats the value using the given formatter.

impl Default for RootAccessTrie

fn default() -> RootAccessTrie

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RootAccessTrie

fn deserialize<__D>( __deserializer: __D, ) -> Result<RootAccessTrie, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RootAccessTrie

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
