Function extern_spec_Shl__ref_i32__ref_usize_shl 

pub fn extern_spec_Shl__ref_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
