sourcefn manage<T>(&self, state: T) -> boolwhere
T: Send + Sync + 'static,
fn manage<T>(&self, state: T) -> boolwhere
T: Send + Sync + 'static,
Add state
to the state managed by the application.
This method can be called any number of times as long as each call
refers to a different T
.
If a state for T
is already managed, the function returns false and the value is ignored.
Managed state can be retrieved by any command handler via the
State
guard. In particular, if a value of type T
is managed by Tauri, adding State<T>
to the list of arguments in a
command handler instructs Tauri to retrieve the managed value.
Panics
Panics if state of type T
is already being managed.
Mutability
Since the managed state is global and must be Send
+ Sync
, mutations can only happen through interior mutability:
use std::{collections::HashMap, sync::Mutex};
use tauri::State;
// here we use Mutex to achieve interior mutability
struct Storage {
store: Mutex<HashMap<u64, String>>,
}
struct Connection;
struct DbConnection {
db: Mutex<Option<Connection>>,
}
#[tauri::command]
fn connect(connection: State<DbConnection>) {
// initialize the connection, mutating the state with interior mutability
*connection.db.lock().unwrap() = Some(Connection {});
}
#[tauri::command]
fn storage_insert(key: u64, value: String, storage: State<Storage>) {
// mutate the storage behind the Mutex
storage.store.lock().unwrap().insert(key, value);
}
tauri::Builder::default()
.manage(Storage { store: Default::default() })
.manage(DbConnection { db: Default::default() })
.invoke_handler(tauri::generate_handler![connect, storage_insert])
// on an actual app, remove the string argument
.run(tauri::generate_context!("test/fixture/src-tauri/tauri.conf.json"))
.expect("error while running tauri application");
Examples
use tauri::{Manager, State};
struct MyInt(isize);
struct MyString(String);
#[tauri::command]
fn int_command(state: State<MyInt>) -> String {
format!("The stateful int is: {}", state.0)

#[tauri::command]

}
tauri::Builder::default()
.setup(|app| {

app.manage(MyString("tauri".into()));
// `MyInt` is already managed, so `manage()` returns false

// read the `MyInt` managed state with the turbofish syntax
