Implementations

impl<T> Loadable<T>

pub fn value(&self) -> Option<&T>

pub fn value_mut(&mut self) -> Option<&mut T>

Mutable access to loaded data, for a list that grows a page at a time rather than being replaced wholesale.

pub fn is_loading(&self) -> bool

pub fn error(&self) -> Option<&str>

pub fn age(&self) -> Option<Duration>

How stale the data is, for the statusline.

pub fn loaded(value: T) -> Self

pub fn begin_refresh(&mut self)

Mark as loading while keeping any value already on screen, so a refresh does not blank the view.
