Module diff 

This module contains datastructures and logic for comparing database privileges, generating, validating and reducing diffs between two sets of database privileges.

Structs

DatabasePrivilegeRowDiff

This struct encapsulates the before and after states of the access privileges for a single user on a single database.

Enums

DatabasePrivilegeChange

This enum represents a change for a single privilege.

DatabasePrivilegesDiff

This enum encapsulates whether a DatabasePrivilegeRow was introduced, modified or deleted.

Functions

create_or_modify_privilege_rows

Converts a set of DatabasePrivilegeRowDiff into a set of DatabasePrivilegesDiff, representing either creating new privilege rows, or modifying the existing ones.

diff_privileges

This function calculates the differences between two sets of database privileges. It returns a set of DatabasePrivilegesDiff that can be used to display or apply a set of privilege modifications to the database.

display_privilege_diffs

Renders a set of DatabasePrivilegesDiff into a human-readable formatted table.

reduce_privilege_diffs

Reduces a set of DatabasePrivilegesDiff by removing any modifications that would be no-ops. For example, if a privilege is changed from Yes to No, but it was already No, that change is removed from the diff.
