[dependabot]

Bumps github.com/open-policy-agent/opa from 0.54.0 to 0.57.0.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v0.57.0

This release contains an updated Rego syntax to allow general references in rule heads, and a mix of new features and bugfixes.

Support for General References in Rule Heads

In OPA 0.56.0, we introduced support for general references in rule heads as an experimental feature. It has now graduated to a fully supported feature, and is no longer experimental.

A general reference is a reference with variables at arbitrary locations. In Rego, partial rules are used for generating sets and objects. In previous versions of OPA, variables were only allowed in the very last position in the rule's reference. Now, Rego has been expanded to allow rules to be declared with general references in their head, with variables at arbitrary locations. This allows for generating nested dynamic object structures:

package example
import future.keywords
Converting a flat list of users to a mapping by "role" and then "id".
users_by_role[role][id] := user if {
some user in data.users
id := user.id
role := user.role
}
Explicit "admin" key override to the above mapping.
users_by_role.admin[id] := user if {
some user in data.admins
id := user.id
}
Leaf entries can be multi-value.
users_by_country[country] contains user.id if {
some user in data.users
country := user.country
}

See the documentation for more information.
