struct Array [src]

This data structure is used by the Zig language code generation and therefore must be kept in sync with the compiler implementation.

Fields

len: comptime_int

child: type

sentinel_ptr: ?*const anyopaqueThe type of the sentinel is the element type of the array, which is the value of the child field in this struct. However there is no way to refer to that type here, so we use *const anyopaque. See also: sentinel.
