Enum Role 

pub enum Role {
    Admin,
    ReadWrite,
    ReadOnly,
}

Database-level roles.

Roles follow a hierarchy: Admin implies ReadWrite implies ReadOnly. Permission checks use the hierarchy via Identity::can_write and Identity::can_admin, but roles are stored explicitly (not inherited) to keep the model simple and auditable.

Variants

Admin

Full administrative access: schema DDL, index management, GC, plus all read-write operations.

ReadWrite

Read and write data: create/update/delete nodes, edges, and properties. Cannot modify schema or indexes.

ReadOnly

Read-only access: MATCH queries, graph traversals, read-only introspection (database stats, schema info).

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Role

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

Formats the value using the given formatter.

impl Display for Role

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

Formats the value using the given formatter.

impl Hash for Role

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Role

fn eq(&self, other: &Role) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
