Struct cedar_policy::Diagnostics

pub struct Diagnostics { /* private fields */ }

Diagnostics providing more information on how a Decision was reached

Implementations

impl Diagnostics

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);
}

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);
}

Trait Implementations

impl Clone for Diagnostics

fn clone(&self) -> Diagnostics

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Diagnostics

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Diagnostics> for Diagnostics

fn from(diagnostics: Diagnostics) -> Self

Converts to this type from the input type.

impl PartialEq for Diagnostics

fn eq(&self, other: &Diagnostics) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
