0.15.1 Changes

var w = file.writer(&b).interface;

Same error as:

0.15.1 Reader/Writer

The key insight you’re missing is that reader() creates a thing that needs to live somewhere. var file_reader = file.reader(&buf); // this var needs the same lifetime as `buf` const reader = &file_reader.interface; // `reader` not reassigned, so use `const`

So use:

var file_writer = file.writer(&b);
const w = &file_writer.interface;
