Struct cedar_policy::Request

pub struct Request(/* private fields */);

Represents the request tuple <P, A, R, C> (see the Cedar design doc).

Implementations

impl Request

pub fn new( principal: Option<EntityUid>, action: Option<EntityUid>, resource: Option<EntityUid>, context: Context, ) -> Self

Create a Request.

Note that you can create the EntityUids using .parse() on any string (via the FromStr implementation for EntityUid). The principal, action, and resource fields are optional to support the case where these fields do not contribute to authorization decisions (e.g., because they are not used in your policies). If any of the fields are None, we will automatically generate a unique entity UID that is not equal to any UID in the store.

pub fn principal(&self) -> Option<&EntityUid>

Get the principal component of the request. Returns None if the principal is “unspecified” (i.e., constructed by passing None into the constructor) or “unknown” (i.e., constructed using the partial evaluation APIs).

pub fn action(&self) -> Option<&EntityUid>

Get the action component of the request. Returns None if the action is “unspecified” (i.e., constructed by passing None into the constructor) or “unknown” (i.e., constructed using the partial evaluation APIs).

pub fn resource(&self) -> Option<&EntityUid>

Get the resource component of the request. Returns None if the resource is “unspecified” (i.e., constructed by passing None into the constructor) or “unknown” (i.e., constructed using the partial evaluation APIs).
