pub struct Diagnostics { /* private fields */ }
Expand description

Diagnostics providing more information on how a Decision was reached

Implementations§

source§

impl Diagnostics

source

pub fn reason(&self) -> impl Iterator<Item = &PolicyId>

Get the PolicyIds of the policies that contributed to the decision. If no policies applied to the request, this set will be empty.

let authorizer = Authorizer::new();
let response = authorizer.is_authorized(&request, &policy, &entities);
match response.decision() {
    Decision::Allow => println!("ALLOW"),
    Decision::Deny => println!("DENY"),
}
println!("note: this decision was due to the following policies:");
for reason in response.diagnostics().reason() {
    println!("{}", reason);
}
source

pub fn errors(&self) -> impl Iterator<Item = &AuthorizationError> + '_

Get the errors that occurred during authorization. The errors should be treated as unordered, since policies may be evaluated in any order.

let authorizer = Authorizer::new();
let response = authorizer.is_authorized(&request, &policy, &entities);
match response.decision() {
    Decision::Allow => println!("ALLOW"),
    Decision::Deny => println!("DENY"),
}
for err in response.diagnostics().errors() {
    println!("{}", err);
}
