Struct RoleGraph 

pub struct RoleGraph {
    pub roles: BTreeMap<String, RoleState>,
    pub grants: BTreeMap<GrantKey, GrantState>,
    pub default_privileges: BTreeMap<DefaultPrivKey, DefaultPrivState>,
    pub memberships: BTreeSet<MembershipEdge>,
}

Complete state of managed roles, grants, default privileges, and memberships.

Both the manifest expander and the database inspector produce this type. The diff engine compares two RoleGraph instances to compute changes.

Fields

roles: BTreeMap<String, RoleState>

Managed roles, keyed by role name.

grants: BTreeMap<GrantKey, GrantState>

Object privilege grants, keyed by grant target.

default_privileges: BTreeMap<DefaultPrivKey, DefaultPrivState>

Default privilege rules, keyed by (owner, schema, type, grantee).

memberships: BTreeSet<MembershipEdge>

Membership edges.

Implementations

impl RoleGraph

pub fn from_expanded( expanded: &ExpandedManifest, default_owner: Option<&str>, ) -> Result<Self, ManifestError>

Build a RoleGraph from an ExpandedManifest.

This converts the manifest’s user-facing types into the normalized model that the diff engine operates on.

Trait Implementations

impl Clone for RoleGraph

fn clone(&self) -> RoleGraph

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoleGraph

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RoleGraph

fn default() -> RoleGraph

Returns the “default value” for a type.
