Description

I write some kind of protocol parser and I use next code to read protocol data:

reader.read_u32_into::<LittleEndian>(&mut buffer);

I would like to use the same logic for writer:

writer.write_u32_from::<LittleEndian>(&buffer);

Is that already possible? Or it needs implementation?

Contributor guide

Research direction
Examine the existing `read u32 into` method in the `WriteBytesExt` trait and implement a corresponding `write u32 from` method by reversing the read logic (i.e., iterating over the buffer and writing each value with the specified endianness).
