Struct casbin::prelude::Enforcer

pub struct Enforcer { /* fields omitted */ }

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

Trait Implementations

impl CoreApi for Enforcer

fn enforce<ARGS: EnforceArgs>(&self, rvals: ARGS) -> 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::prelude::*;
#[cfg(feature = "runtime-async-std")]
#[async_std::main]
async fn main() -> Result<()> {
    let mut e = Enforcer::new("examples/basic_model.conf", "examples/basic_policy.csv").await?;
    assert_eq!(true, e.enforce(("alice", "data1", "read"))?);
    Ok(())
}

#[cfg(feature = "runtime-tokio")]
#[tokio::main]
async fn main() -> Result<()> {
    let mut e = Enforcer::new("examples/basic_model.conf", "examples/basic_policy.csv").await?;
    assert_eq!(true, e.enforce(("alice", "data1", "read"))?);

    Ok(())
}
