Trait AuthEngine 

pub trait AuthEngine:
    Send

    + Default {
    // Required methods
    fn authenticate(&self, username: &str, password: &str) -> AuthResult<()>;
    fn user_exists(&self, username: &str) -> AuthResult<bool>;
}

Trait for authentication engines.

Implementations of this trait provide different authentication backends, such as in-memory storage, databases, LDAP, etc.

Required Methods

fn authenticate(&self, username: &str, password: &str) -> AuthResult<()>

Authenticates a user with the given username and password.

Returns Ok(()) if authentication succeeds, or an error if authentication fails (AuthError::InvalidCredentials for wrong password, AuthError::UserNotFound for non-existent user).

fn user_exists(&self, username: &str) -> AuthResult<bool>

Checks if a user exists in the authentication store.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
