write u8 array to file

[calm fable]

I have the same issue as [here](#1239248126167093309 message), but then the other way around. If I pass a u8[] directly to std::file::write, I get an error about passing an argument of type '???'. Using the converter the other way around, no data is being written to the files.

Passing arrays around to functions is kinda iffy sadly

It should work if you wrap the array in a struct and give it that

[calm fable]

struct ArrayHolder<auto size>
{
    u8 data[size];
};

ArrayHolder<current.compressedSize> holder;
holder.data = fileData;
std::file::write(writeFileHandle, holder);

gives the same error as passing an array

std::file::write only accepts strings afaik

however the docs say:

data: String or Pattern to write to the file

so it may be a bug

[calm fable]

is there a way to convert a u8 array to a str? Using the converter the other way around doesn't work.

[wraith osprey]

maybe a union of u8 and char to create a char array which is internally converted to a string.

there's also std::mem::Reinterpreter

[calm fable]

that works!

reinterpreter is

 union Reinterpreter<From, To> {
        From from;
        To to;
    };
