Implementation

pub fn Child(comptime T: type) type {
    return switch (@typeInfo(T)) {
        .array => |info| info.child,
        .vector => |info| info.child,
        .pointer => |info| info.child,
        .optional => |info| info.child,
        else => @compileError("Expected pointer, optional, array or vector type, found '" ++ @typeName(T) ++ "'"),
    };
}
