bytewriter

Package bytewriter implements writers that support concurrent writing within a fixed length block

initially tried to use bytes.Buffer but the main restriction with that is that it does not allow the freedom to move around in the buffer. Further, it always writes at the end of the buffer

another attempt was to maintain a position identifier that was always passed to any function that wrote anything and the function had to return the next writable location, which resulted in calls like

pos = writeString(buffer, pos, "mmv")

which became unmaintainable after a while, and along with all the side maintainance looked extremely ugly

then implemented a minimal buffer wrapper that gives the freedom to move around and write anywhere you want, which worked if you only need one position identifier, i.e. only one write operation happens at a time

this implements a writer that supports multiple concurrent writes within a fixed length block
