ownership cleanup
Learn ownership cleanup in Zig with a construct-specific explanation, unique example, engineering boundary, and mastery check.
ownership cleanup is a focused Zig topic inside Memory. This lesson explains the construct itself, the state or value it operates on, and the observable result it produces.
Read the example as a small executable experiment. Identify the exact syntax that belongs to ownership cleanup, then change one input and predict the result before running it.
Topic-specific example
const mem=try allocator.alloc(u8,16); defer allocator.free(mem);
ownership cleanup has rules that are easy to miss when the example is copied mechanically. Check the feature-specific boundary shown by this construct: scope, mutability, evaluation order, type constraints, lifetime, error behavior, compile-time restrictions, or resource cleanup where applicable.
