Function extern_spec_Shl__ref_usize__ref_u16_shl 

pub fn extern_spec_Shl__ref_usize__ref_u16_shl(self_: &u16, rhs: &usize) -> u16

extern spec for <&u16 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
