Struct MemoryAuth 

pub struct MemoryAuth { /* private fields */ }

Simple in-memory authentication backend using a hash set.

This is suitable for small deployments with a fixed set of users. For dynamic user management or large user bases, consider using a database-backed backend.

Implementations

impl MemoryAuth

pub fn new() -> Self

Create a new empty auth backend.

pub fn from_hashes<I, S>(hashes: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Create from pre-computed SHA224 hashes.

Example

use trojan_auth::MemoryAuth;

let auth = MemoryAuth::from_hashes(["abc123...", "def456..."]);

pub fn from_passwords<I, S>(passwords: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Create from plaintext passwords (will be hashed).

Example

use trojan_auth::MemoryAuth;

let auth = MemoryAuth::from_passwords(["password1", "password2"]);

pub fn from_passwords_with_ids<I, P, U>(pairs: I) -> Self

where I: IntoIterator<Item = (P, U)>, P: AsRef<str>, U: Into<String>,

Create from password-to-user-id pairs.

Example

use trojan_auth::MemoryAuth;

let auth = MemoryAuth::from_passwords_with_ids([
    ("password1", "user1"),
    ("password2", "user2"),
]);

pub fn add_password(&mut self, password: &str, user_id: Option<String>)

Add a user with a plaintext password.

pub fn add_hash(&mut self, hash: String, user_id: Option<String>)

Add a user with a pre-computed hash.

pub fn remove_hash(&mut self, hash: &str) -> bool

Remove a user by hash.

pub fn len(&self) -> usize

Get the number of registered users.

pub fn is_empty(&self) -> bool

Check if no users are registered.

pub fn contains(&self, hash: &str) -> bool

Check if a hash is registered.
