Zig 0.17.0-dev (Split by item)

This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig library itself.

panic

This namespace is used by the Zig compiler to emit various kinds of safety panics. These can be overridden by making a public panic namespace in the root source file.
