How to walk directories?

Help
1

Hi, I am trying to walk directories using walk function from stdlib. However, I don’t know the correct way to use it. Use the following code gives me error blablabla does not support field access

zig version: 0.9.1

Code:

const std = @import("std");
const fs = std.fs;

pub fn main() !void {
    const allocator = std.testing.allocator;

    const dir = try fs.cwd().openDir(".", .{ .iterate = true });
    var walker = dir.walk(allocator);
    defer walker.deinit();

    while (try walker.next()) |entry| {
        std.debug.print("{s}\n", .{entry.basename});
    }
}

Error:

./src/main.zig:29:22: error: type '@typeInfo(@typeInfo(@TypeOf(std.fs.Dir.walk)).Fn.return_type.?).ErrorUnion.error_set!std.fs.Walker' does not support field access
    while (try walker.next()) |entry| {
                     ^

It seems walker here is an error union, instead use

var walker = try dir.walk(allocator);
