Struct UserStorage 

pub struct UserStorage { /* private fields */ }

Manages user accounts and role assignments in memory.

Implementations

impl UserStorage

pub fn new() -> UserStorage

Create a new user storage instance.

pub fn clear(&self)

Clear all users.

pub fn len(&self) -> usize

Number of users.

pub fn is_empty(&self) -> bool

Whether no user exists (used for admin seeding).

pub fn save_to_dir<P>(&self, path: P) -> Result<(), StorageError>

where P: AsRef<Path>,

Persist users to a directory snapshot.

The snapshot is plaintext JSON holding bcrypt password hashes. Writes are atomic (tmp file plus rename) but carry no encryption and no explicit file mode: the file inherits the process umask, so operators must restrict the directory permissions. At-rest encryption is tracked as an independent issue and deliberately out of scope here.

pub fn load_from_dir<P>(&self, path: P) -> Result<(), StorageError>

where P: AsRef<Path>,

Load users from a directory snapshot.

pub fn change_password(&self, info: &PasswordInfo) -> Result<bool, StorageError>

Change the user password.

pub fn create_user(&self, info: &UserInfo) -> Result<bool, StorageError>

Create a new user.

Returns Ok(true) when the user was inserted, Ok(false) when the username already exists (the existing account is left untouched). The caller decides whether a duplicate is an error (CREATE USER) or silently acceptable (IF NOT EXISTS).

pub fn alter_user(&self, info: &UserAlterInfo) -> Result<bool, StorageError>

Modify user information.

pub fn drop_user(&self, username: &str) -> Result<bool, StorageError>

Delete the user.

pub fn update_last_login(&self, username: &str) -> Result<bool, StorageError>

Record a successful login timestamp.

pub fn get_user(&self, username: &str) -> Option<UserInfo>

Get user information.

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

Check whether the user exists.

pub fn list_users(&self) -> Vec<String>

List all usernames, sorted.

pub fn grant_role( &self, username: &str, space_id: i64, role: RoleType, ) -> Result<bool, StorageError>

Grant roles to user and persist the space to role mapping.

pub fn revoke_role( &self, username: &str, space_id: i64, ) -> Result<bool, StorageError>

Revoke roles from user and drop the persisted mapping.

pub fn get_user_roles(&self, username: &str) -> HashMap<i64, RoleType>

Role mapping of a single user.

pub fn list_all_roles(&self) -> HashMap<String, HashMap<i64, RoleType>>

All persisted role mappings.

Trait Implementations

impl Clone for UserStorage

fn clone(&self) -> UserStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UserStorage

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

Formats the value using the given formatter.

impl Default for UserStorage

fn default() -> UserStorage

Returns the “default value” for a type.
