File Write #8
Description
webfsim.FileWriteAt is the function.
Given a file, a buffer, and an offset return a new file with the buffer written starting at that offset.
It might be worth looking at how other file systems do this.
It seems like every write could require replacing 0 or more data blobs, and inserting 0 or 1 data blobs. Will probably require adding some utility methods to the btree or btree iterator.
Not sure how important this. I don't know how many people would be working out of FUSE in the near future. As opposed to importing whole files to read from other devices later.
