Struct titanium::desktop::gui::libdruid::widget::DefaultScopePolicy

pub struct DefaultScopePolicy<F, Transfer>where
    F: FnOnce(<Transfer as ScopeTransfer>::In) -> <Transfer as ScopeTransfer>::State,
    Transfer: ScopeTransfer,{ /* private fields */ }

A default implementation of ScopePolicy that takes a function and a transfer.

Implementations

impl<F, Transfer> DefaultScopePolicy<F, Transfer>where F: FnOnce(<Transfer as ScopeTransfer>::In) -> <Transfer as ScopeTransfer>::State, Transfer: ScopeTransfer,

pub fn new(make_state: F, transfer: Transfer) -> DefaultScopePolicy<F, Transfer>

Create a ScopePolicy from a factory function and a ScopeTransfer.

impl<F, L, In, State> DefaultScopePolicy<F, LensScopeTransfer<L, In, State>>where F: FnOnce(In) -> State, L: Lens<State, In>, In: Data, State: Data,

pub fn from_lens( make_state: F, lens: L ) -> DefaultScopePolicy<F, LensScopeTransfer<L, In, State>>

Create a ScopePolicy from a factory function and a lens onto that Scope’s state.

Trait Implementations

impl<F, Transfer> ScopePolicy for DefaultScopePolicy<F, Transfer>where F: FnOnce(<Transfer as ScopeTransfer>::In) -> <Transfer as ScopeTransfer>::State, Transfer: ScopeTransfer,

type In = <Transfer as ScopeTransfer>::In

The type of data that comes in from the surrounding application or scope.

type State = <Transfer as ScopeTransfer>::State

The type of data that the Scope will maintain internally. This will usually be larger than the input data, and will embed the input data.

type Transfer = Transfer

The type of transfer that will be used to synchronise internal and application state

fn create( self, input: &<DefaultScopePolicy<F, Transfer> as ScopePolicy>::In ) -> (<DefaultScopePolicy<F, Transfer> as ScopePolicy>::State, <DefaultScopePolicy<F, Transfer> as ScopePolicy>::Transfer)

Make a new state and transfer from the input.
