Struct RoleValidator 

pub struct RoleValidator {}

The RoleValidator validates a role expression with a set of role names.

Roles are typically assigned to a user during an authentication process.

Example

Let’s say a user authenticates and is given the roles user, subscribed and student.

For those the role expression user, teacher is invalid while the expression user,teacher; subscribed is valid.

Implementations

impl RoleValidator

pub fn is_valid(roles: &HashSet<String>, role_expr: &RoleExpr) -> bool

Return true, if role expression is valid.
