Struct User 

pub struct User {
    pub id: i64,
    pub identity_hash: [u8; 32],
    pub auth_verifier: String,
}

Represents a registered user in the system.

Users are identified by an identity_hash (a hash of their public identity) and authenticated via an auth_verifier. Neither field stores a raw password. This keeps the server from ever knowing who the user actually is.

Fields

id: i64

identity_hash: [u8; 32]

auth_verifier: String

Implementations

impl User

pub async fn create( pool: &SqlitePool, identity_hash: &Vec<u8>, auth_verifier: String, ) -> Result<()>

Inserts a new user into the users table via the provided SqlitePool.

Both identity_hash and auth_verifier are expected to be pre-processed on the client side before being sent to this function.

Errors

• Returns [sqlx::Error::Database] on a uniqueness violation, meaning a user with the same identity_hash already exists.
• Returns [sqlx::Error] if the database query fails for any other reason.

pub async fn verify( pool: &SqlitePool, identity_hash: Vec<u8>, auth_verifier: String, ) -> Result<Option<i64>>

Verifies the credential pair (identity_hash and auth_verifier) against the database.

Returns Some(user_id) if a matching user is found, or None if the credentials do not match any existing record. This is the primary authentication check used by the login endpoint.

Errors

• Returns [sqlx::Error] if the database query fails.
