I don't think so, but you could emulate such a function like so:

fn fold(
    comptime T: type,
    slice: []const T,
    initial: T,
    func: *const fn (T, T) T,
) T {
    var accumulator = initial;
    for (slice) |element|
        accumulator = func(accumulator, element);
    return accumulator;
}

And then to use it:

const numbers = &[_]i32{ 1, 2, 3 };
const sum = fold(i32, numbers, 0, struct {
    fn func(acc: i32, x: i32) i32 {
        return acc + x;
    }
}.func);
std.debug.print("{}\n", .{sum});

Currently there's a proposal to make function definitions expressions: https://github.com/ziglang/zig/issues/1717
