Function extern_spec_Shl__ref_usize__ref_isize_shl 

pub fn extern_spec_Shl__ref_usize__ref_isize_shl(
    self_: &isize,
    rhs: &usize,
) -> isize

extern spec for <&isize as Shl<&usize>>::shl

This is not a real function: its only use is for documentation.

requires

(0usize as $rhs) <= *rhs && *rhs < $type::BITS as $rhs

ensures

result == *self $op *rhs
