Struct Role 

pub struct Role {
    pub name: String,
    pub permissions: BTreeSet<Permission>,
}

A named bundle of permissions.

Fields

name: String

Role name (e.g. admin).

permissions: BTreeSet<Permission>

Permissions granted by this role.

Implementations

impl Role

pub fn allows(&self, p: Permission) -> bool

Whether this role grants permission p.

pub fn admin() -> Role

Builtin admin role: all permissions.

pub fn readwrite() -> Role

Builtin readwrite role: read + write + schema definition. An application-tier user is expected to create and evolve its own tables and indexes, so readwrite includes Ddl. It does NOT include Admin (user/role management stays admin-only).

pub fn readonly() -> Role

Builtin readonly role: read only.

pub fn builtin(name: &str) -> Option<Role>

Resolve a builtin role by name, or None if it is not a builtin.
