Struct MemoryAuthEngine 

pub struct MemoryAuthEngine { /* private fields */ }

In-memory authentication engine using a HashMap.

This is a simple authentication engine that stores credentials in memory. Useful for testing and simple deployments.

Implementations

impl MemoryAuthEngine

pub fn new() -> Self

Creates a new empty MemoryAuthEngine.

pub fn from_map(credentials: HashMap<String, String>) -> Self

Creates a MemoryAuthEngine from an existing HashMap.

pub fn from_arc(credentials: Arc<HashMap<String, String>>) -> Self

Creates a MemoryAuthEngine from an Arc.

pub fn from_file(path: &str) -> Result<Self>

Loads credentials from a file.

The file should be formatted as:

username:password
username2:password2

Returns an error if the file cannot be read.

pub fn add_user(&mut self, username: String, password: String)

Adds a user to the credential store.

Note: This requires mutable access and will clone the internal HashMap.

pub fn len(&self) -> usize

Returns the number of users in the store.

pub fn is_empty(&self) -> bool

Returns true if the store is empty.
