A better way of saying it is that Rust makes lifetimes implicit (by default), but in some cases it is necessary to manually manage lifetimes in Rust, when there's ambiguity the compiler can't resolve on its own.

In Zig and C, it's always expected that you will explicitly manage your lifetimes. Zig uses the allocator interface to explicitly allocate new buffer or heap values and its keyword 'defer' to clean up allocated variables after the scope exits so that allocations and frees generally live next to each other.

C on the other hand, is relatively unopinionated about how lifetimes are managed. The defer keyword honestly takes most of the pain of managing lifetimes away.
