Struct OptionOf 

Source 
pub struct OptionOf<M>(/* private fields */);
Expand description

Marks the impl for Option<S>, where S’s own marker is M.

Trait Implementations§

Source§

impl<State: 'static, M, S: ViewSeq<State, M>> ViewSeq<State, OptionOf<M>> for Option<S>

Source§

fn extend_views(self, out: &mut Vec<AnyView<State>>)

Push every element of this sequence, in order, onto out — erasing each with AnyView::new (a no-op for an element already an AnyView).
