Struct cursive::views::IdView

pub struct IdView<V: View> { /* fields omitted */ }

Wrapper around a view to provide interior mutability.

Methods

impl<V: View> IdView<V>

pub fn new<S: Into<String>>(id: S, view: V) -> Self

Wraps view in a new IdView.

pub fn get_mut(&mut self) -> ViewRef<V>

Gets mutable access to the inner view.

This returns a ViewRef<V>, which implement DerefMut<Target = V>.

Panics

Panics if another reference for this view already exists.
