Struct casbin::Enforcer

pub struct Enforcer<A: Adapter> { /* fields omitted */ }

Enforcer is the main interface for authorization enforcement and policy management.

Methods

impl<A: Adapter> Enforcer<A>

pub fn new(m: Model, a: A) -> Self

Enforcer::new creates an enforcer via file or DB.

pub fn add_function(&mut self, fname: &str, f: fn(_: String, _: String) -> bool)

pub fn enforce(&self, rvals: Vec<&str>) -> Result<bool>

Enforce decides whether a "subject" can access a "object" with the operation "action", input parameters are usually: (sub, obj, act).

Examples

use casbin::{Enforcer, Model, FileAdapter};

let m = Model::from_file("examples/basic_model.conf").unwrap();
let adapter = FileAdapter::new("examples/basic_policy.csv");
let e = Enforcer::new(m, adapter);
assert_eq!(true, e.enforce(vec!["alice", "data1", "read"]).unwrap());
