hello,

.zig/lib/std/Io/File.zig:225:16: error: no field or member function named 'fileWriteStreaming' in 'Io.File'
    return file.fileWriteStreaming(io, buffer);

if use :

const byte: []const u8 = std.fmt.allocPrint(allocTest,"{s}", .{"hello"}) catch unreachable;

var hello = [1][]const u8 {byte};

_ = std.Io.File.writeStreaming(filePhy,io,&hello) catch unreachable;

It is unclear what you are trying to do.
What do you want to do?

Do you want to write to a file?

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

pub fn main() !void {
    // NOTE truncate needs to be false if you want to append
    const example = try std.fs.cwd().createFile("example.txt", .{ .truncate = false });
    defer example.close();

    var buffer: [512]u8 = undefined;
    var writer = example.writer(&buffer);
    try writer.seekTo(try writer.file.getEndPos()); // NOTE set position to end (if you want to append)

    const out: *Io.Writer = &writer.interface;

    try out.print("hello\n", .{});
    // or
    try out.writeAll("hello\n");

    try out.flush();
}

Yes, that was the case in 15.2,
but not in 16.0.dev.

try std.fs.cwd().createFile

deprecated

Writing for Io.File is not implemented yet. std.Io.File and std.Io.Dir are very incomplete at the moment.

I’ve been racking my brains over this.
Very serious…
Glad to have it confirmed.
