Trait ExecSpecSeqDropLast 

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

    // Required method
    exec fn exec_drop_last(self) -> Self;
}
Expand description

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§

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

Source§

exec fn exec_drop_last(self) -> res : Self
