[−][src]Struct druid::widget::LensScopeTransfer
A ScopeTransfer that uses a Lens to synchronise between a large internal
state and a small input.
Implementations
impl<L: Lens<State, In>, In, State> LensScopeTransfer<L, In, State>[src]
pub fn new(lens: L) -> Self[src]
Create a ScopeTransfer from a Lens onto a portion of the Scope's state.

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