DeviceManager

Struct DeviceManager 

Source
pub struct DeviceManager {
    pub devices: Vec<Device>,
    /* private fields */
}
Expand description

Gerencia múltiplos devices: carrega configs JSON, conecta, despacha eventos.

§Uso básico

let mut manager = DeviceManager::new("examples/devices/configs");
manager.load_devices();
manager.connect_devices(false).await;

Fields§

§devices: Vec<Device>

Devices carregados.

Implementations§

Source§

impl DeviceManager

Source

pub fn new<P: AsRef<Path>>(devices_path: P) -> Self

Cria um manager apontando para devices_path.

Source

pub fn with_event_handler(self, handler: SharedEventHandler) -> Self

Define o handler de eventos (builder-style).

Source

pub fn set_event_handler(&mut self, handler: SharedEventHandler)

Substitui o handler de eventos.

Source

pub fn load_devices(&mut self)

Lê os arquivos .json de devices_path e popula self.devices.

Cada arquivo deve ter um campo "reader" ("X714" ou "R700_IOT"). O nome do arquivo (sem .json) vira o name do device. Todos os outros campos são opcionais — padrões são aplicados automaticamente. Chama assign_event_handler() ao final.

Source

pub fn add_device( &mut self, name: &str, device_type: &str, data: HashMap<String, Value>, )

Adiciona um device a partir de parâmetros já parseados.

O campo "name" é injetado automaticamente a partir do nome do arquivo. Campos não informados usam os padrões de cada device.

Source

pub fn assign_event_handler(&mut self)

Atribui o handler de eventos a todos os devices carregados.

Source

pub async fn connect_devices(&mut self, force: bool)

Conecta todos os devices em background (tasks tokio).

  • Se já existirem tasks ativas e force for false, é um no-op.
  • Se force for true, cancela as tasks anteriores, desconecta os devices, recarrega os JSONs e reconecta tudo.
Source

pub async fn cancel_connect_tasks(&mut self)

Cancela todas as tasks de conexão ativas.

Source

pub async fn disconnect_devices(&mut self)

Fecha todos os devices e limpa a lista.

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

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

Retorna os nomes de todos os devices carregados.

Source

pub fn get_device(&self, name: &str) -> Option<&Device>

Retorna referência para um device pelo nome.

Source

pub fn get_device_mut(&mut self, name: &str) -> Option<&mut Device>

Retorna referência mutável para um device pelo nome.

Source

pub fn get_device_info(&self, name: Option<&str>) -> Vec<DeviceInfo>

Snapshot de estado de um ou todos os devices.

Se name for None, retorna info de todos.

Source

pub fn any_device_reading(&self) -> bool

true se pelo menos um device está conectado e lendo.

Source

pub fn get_serial_number(&self, name: &str) -> Option<String>

Retorna o número de serial do device (apenas se conectado).

Source

pub async fn start_inventory(&self, name: &str) -> Result<(), String>

Inicia inventário em um device específico.

Source

pub async fn stop_inventory(&self, name: &str) -> Result<(), String>

Para inventário em um device específico.

Source

pub async fn start_inventory_all(&self) -> HashMap<String, bool>

Inicia inventário em todos os devices RFID conectados. Retorna mapa name → ok.

Source

pub async fn stop_inventory_all(&self) -> HashMap<String, bool>

Para inventário em todos os devices RFID conectados. Retorna mapa name → ok.

Source

pub async fn write_epc( &self, name: &str, target_identifier: Option<&str>, target_value: Option<&str>, new_epc: &str, password: &str, ) -> Result<(), String>

Escreve um novo EPC em uma tag.

  • target_identifier: Some("epc") ou Some("tid") (filtra a tag alvo); None = qualquer tag.
  • target_value: valor do identificador alvo (obrigatório quando target_identifier é Some).
Source

pub async fn write_gpo( &self, name: &str, pin: u8, state: bool, control: &str, time_ms: u64, ) -> Result<(), String>

Controla um pino GPO.

  • control: "static" ou "pulsed"
  • time_ms: duração do pulso (ignorado em modo "static")
