Struct AuthenticationEvaluator 

pub struct AuthenticationEvaluator<S>
where
    S: AuthenticationStrategy,
{ /* private fields */ }

Authentication evaluator - main entry point for authentication.

This struct acts as a facade, delegating authentication evaluation to the configured authentication strategy.

Design

• Facade Pattern: Simplifies authentication API for clients
• Strategy Pattern: Delegates to pluggable authentication strategies
• Thread-safe: Can be safely shared across threads

Example

use rocketmq_auth::AuthenticationEvaluator;
use rocketmq_auth::StatelessAuthenticationStrategy;
use rocketmq_auth::AuthConfig;

let config = AuthConfig::default();
let strategy = StatelessAuthenticationStrategy::new(config, None);
let evaluator = AuthenticationEvaluator::new(strategy);

// Evaluate authentication
evaluator.evaluate(&context)?;

Implementations

impl<S> AuthenticationEvaluator<S>

where S: AuthenticationStrategy,

pub fn new(authentication_strategy: S) -> Self

Create a new authentication evaluator with the given strategy.

Arguments

• authentication_strategy - The authentication strategy to use

Example

let strategy = StatelessAuthenticationStrategy::new(config, provider);
let evaluator = AuthenticationEvaluator::new(strategy);

pub async fn evaluate( &self, context: &dyn AuthenticationContext, ) -> AuthServiceResult<()>

Evaluate authentication for the given context.

This method delegates to the underlying authentication strategy. Returns Ok(()) if authentication succeeds, or an AuthServiceError if it fails.

Arguments

• context - The authentication context containing request information

Returns

• Ok(()) - Authentication succeeded
• Err(AuthServiceError) - Authentication failed with a specific error

Example

let context = DefaultAuthenticationContext::new();
evaluator.evaluate(&context)?;

pub fn strategy(&self) -> &S

Get a reference to the underlying authentication strategy.
