Struct cedar_policy_core::entities::EntityJsonParser

pub struct EntityJsonParser<'e, 's, S: Schema = NullSchema> { /* private fields */ }

Struct used to parse entities from JSON.

Implementations

impl<'e, 's, S: Schema> EntityJsonParser<'e, 's, S>

pub fn new( schema: Option<&'s S>, extensions: Extensions<'e>, tc_computation: TCComputation ) -> Self

Create a new EntityJsonParser.

If a schema is provided, this will inform the parsing: for instance, it will allow __entity and __extn escapes to be implicit, and it will error if attributes have the wrong types (e.g., string instead of integer). That does not mean it will fully enforce that the produced Entities conform to the schema – for instance, as of this writing, it will not error for unexpected (additional) record attributes.

If you pass TCComputation::AssumeAlreadyComputed, then the caller is responsible for ensuring that TC holds before calling this method.

pub fn from_json_str(&self, json: &str) -> Result<Entities, EntitiesError>

Parse an entities JSON file (in &str form) into an Entities object

pub fn from_json_value(&self, json: Value) -> Result<Entities, EntitiesError>

Parse an entities JSON file (in serde_json::Value form) into an Entities object

pub fn from_json_file(&self, json: impl Read) -> Result<Entities, EntitiesError>

Parse an entities JSON file (in std::io::Read form) into an Entities object
