Struct AccessTrie

Source 
pub struct AccessTrie<T = ()> { /* private fields */ }
Available on crate feature entity-manifest only.
Expand description

A Trie representing a set of data paths to load, starting implicitly from a Cedar value.

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§

Source§

impl<T> AccessTrie<T>
where T: Clone,

Source

pub fn children(&self) -> &HashMap<SmolStr, Box<AccessTrie<T>>>

Get the children of this AccessTrie.

Source

pub fn ancestors_required(&self) -> bool

Get a boolean which is true if this trie requires all ancestors of the entity to be loaded.

Source

pub fn data(&self) -> &T

Get the data associated with this AccessTrie. This is usually () unless it is annotated by a type.
