Function extern_spec_Shl_i32__ref_usize_shl 

pub fn extern_spec_Shl_i32__ref_usize_shl(self_: &usize, rhs: i32) -> usize

extern spec for <&usize as Shl<i32>>::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
