chore(deps): bump cedar-policy from 3.4.1 to 4.4.0 in /packages/cedar_ffi/src

[dependabot]

Bumps cedar-policy from 3.4.1 to 4.4.0.

Release notes

Sourced from cedar-policy's releases.

v4.4.0

Release 4.4.0, available on crates.io

Cedar Language Version: 4.3

Added

• Stabilized RFC 76, removing the experimental level-validate feature flag. That functionality is now available without the feature flag. Stabilization comes with changes to fix bugs in the features. Level validation is now more permissive when checking if expressions (fixing #1507), and stricter when checking record literals and entity tag operations (fixing #1505 and #1503). (#1567)
• Implemented RFC 53 (enumerated entity types) (#1377)
• Stabilized RFC 80 (datetime extension), making datetime a default feature. (#1541)
• Added Entities::remove_entities() to remove Entitys from an Entities struct (#1453, resolving #701)
• Added PolicySet::merge() to merge a PolicySet into another PolicySet struct (#1476, resolving #610)
• Added to_cedar functions for PolicySet, Policy, and Template that render the policy in the Cedar syntax. These functions can be used to convert JSON formatted policies into the human-readable syntax (#1510, resolving #461)
• Added Validator::schema() to get a reference to the Schema even after it has been consumed to construct a Validator (#1524)
• Added Schema::request_envs() to get all of the RequestEnvs that are valid according to the schema. (This joins the existing Policy::get_valid_request_envs() and Template::get_valid_request_envs() that return the subset of request envs that are valid for a particular policy or template.) (#1547)
• Added EntityId::unescaped(), analogous to EntityId::escaped(). This is simply an alias for EntityId::as_ref() with the AsRef impl that produces &str. (#1555)
• Added PartialResponse::unknown_entities method (#1557)
• Added Entities::len and Entities::is_empty methods (#1562, resolving #1523)

Changed

• Changed Entities::add_entities and Entities::from_entities to ignore structurally equal entities with the same Entity UID.
• For protobufs experimental feature, a number of changes to the interface and the Protobuf format definitions, as we continue to iterate towards making this feature stable. (#1488, #1495, #1506, #1535)
• Bump MSRV to 1.81 (#1542)
• HierarchyNotRespected validation error is no longer returned (although the error variant remains, to avoid a breaking change). This means that in some edge cases, policies that previously failed to validate under strict validation will now pass validation, probably with an ImpossiblePolicy warning. (#1355, resolving #638)

v4.3.3

Release 4.3.3, available on crates.io

Changed

• Significant changes to the API for the experimental protobufs feature (#1452, #1467, others)

Fixed

• Fixed the experimental protobufs feature so that code depending on cedar-policy with this feature now successfully builds, even if that code is not part of the same Cargo workspace as cedar-policy, cedar-policy-core, etc (#1452).
• Fixed a bug in the experimental entity-manifest feature. If an entity appears as both a possible value for a scope variable and an entity literal, slicing using entity manifests will now correctly capture all necessary attributes (#1429).
• Fixed a bug in the experimental entity-manifest and level-validate features. These features failed to consider any attribute accesses occurring inside the guard of an if expression when guard expression had a singleton boolean type (#1462).

v4.3.2

Release 4.3.2, available on crates.io
