Enum RoleType 

pub enum RoleType {
    God = 1,
    Admin = 2,
    Dba = 3,
    User = 4,
    Guest = 5,
}

5-level permission model - reference nebula-graph implementation

• God: global super administrator with all privileges (similar to Linux root)
• Admin: Space administrator who can manage Schema and users in Space.
• Dba: Database administrator who can modify the Schema.
• User: Normal user, can read and write data
• Guest: read-only user, can only read data

Variants

God = 1

Admin = 2

Dba = 3

User = 4

Guest = 5
