Trait ExecSpecSeqLast 

Source 
pub trait ExecSpecSeqLast<'a>: Sized + DeepView<V = Seq<<Self::Elem as DeepView>::V>> {
    type Elem: DeepView;

    // Required method
    exec fn exec_last(self) -> Self::Elem;
}
Expand description

Spec for executable version of Seq::last.

Required Associated Types§

Source

type Elem: DeepView

Required Methods§

Source

exec fn exec_last(self) -> Self::Elem

requires
0 < self.deep_view().len(),

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types§

Source§

impl<'a, T: DeepView> ExecSpecSeqLast<'a> for &'a [T]

Source§

exec fn exec_last(self) -> res : Self::Elem

ensures
res.deep_view() == self.deep_view().last(),
Source§

type Elem = &'a T
