Struct cursive::views::LastSizeView

pub struct LastSizeView<T> {
    pub view: T,
    pub size: XY<usize>,
}

Wrapper around a view that remembers its size.

Fields

view: T

Wrapped view.

size: XY<usize>

Cached size from the last layout() call.

Implementations

impl<T> LastSizeView<T>

pub fn new(view: T) -> LastSizeView<T>

Wraps the given view.

pub fn get_inner(&self) -> &T

Gets access to the inner view.

pub fn get_inner_mut(&mut self) -> &mut T

Gets mutable access to the inner view.

Trait Implementations

impl<V> Default for LastSizeView<V> where
    V: Default, 

pub fn default() -> LastSizeView<V>

Returns the "default value" for a type.

impl<T> ViewWrapper for LastSizeView<T> where
    T: View, 

type V = T

Type that this view wraps.

pub fn with_view<F, R>(&self, f: F) -> Option<R> where
    F: FnOnce(&<LastSizeView<T> as ViewWrapper>::V) -> R,

pub fn with_view_mut<F, R>(&mut self, f: F) -> Option<R> where
    F: FnOnce(&mut <LastSizeView<T> as ViewWrapper>::V) -> R, 

Runs a function on the inner view, returning the result.

pub fn into_inner(
    self
) -> Result<<LastSizeView<T> as ViewWrapper>::V, LastSizeView<T>> where
