Zig 0.15 ArrayList API Helper FAQs

Question 1

Why did Zig move to explicit allocator passing?

Accepted Answer

This change makes memory allocations more explicit in the code, improving readability regarding where memory is touched and allowing different allocators to be used for different operations on the same list.

Question 2

How do I fix the 'no member named init' error in Zig?

Accepted Answer

This error occurs when using pre-0.15 syntax. To fix it, remove the .init(allocator) call and use the struct initialization syntax '{}', then pass your allocator to methods like .append().

Question 3

Does this skill support the Zig 0.15 deinit method?

Accepted Answer

Yes, it provides the correct syntax for deinit(allocator), ensuring that memory is properly freed using the same explicit pattern as the rest of the API.

Question 4

How do I initialize an ArrayList in Zig 0.15?

Accepted Answer

You initialize it as an empty struct using 'var list = std.ArrayList(T){};' instead of calling a dedicated init function with an allocator.

Question 5

What changed in the Zig 0.15 ArrayList API?

Accepted Answer

In Zig 0.15, the allocator is no longer passed during initialization. It must now be provided as an argument to every method call that performs an allocation or deallocation.
