You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: non_fallible_api.rs
    path of file: ./repos/ink/linting/extra/ui/pass
    
    the code of the file until where you have to start completion: #![cfg_attr(not(feature = "std"), no_std, no_main)]

use ink_primitives::AccountId;

pub type TyAlias1 = AccountId;
pub type TyAlias2 = TyAlias1;

#[ink::c
    
        pub fn non_fallible_statically_known(&mut self, a: AccountId, b: AccountId) {
            // Mapping
            let _ = self.map_1.insert(a, &b);
            let _ = self.map_1.get(a);
            let _ = self.map_1.take(a);
            let _ = self.map_2.insert(a, &[b; 1]);
            let _ = self.map_3.insert(a, &(b, b));

            // Lazy
            let _ = self.lazy_1.get();
            self.lazy_1.set(&a);
            let _ = self.lazy_2.get();
            self.lazy_2.set(&a);

            // StorageVec
            let _ = self.vec_1.peek();
            let _ = self.vec_1.get(0);
            self.vec_1.set(0, &a);
            let _ = self.vec_1.pop();
            self.vec_1.push(&a);
        }
