Vectored I/O with heterogeneous collection of buffer types

[tpambor]

Hello,

my use case involves vectored I/O where the individual buffers are of different types. For example, one part of the data to be written might be a statically allocated array, another a Vec. Conceptually, I thought about representing this as a tuple (buffer1, buffer2, etc.) and use it with a vectored write operation. But I've run into the problem that for IoVectoredBuf all items must be of the same type.

Is there an existing pattern or recommended approach for performing vectored I/O with a heterogeneous collection of buffer types that I might have missed?

Would it be feasible to extend compio to support this use case?

That needs refactoring. @George-Miao what do you think?
