Package kv supporting read and write of a simple file formating for Sophie, which
stores key-value pairs.
KVFile format:
vint(key-len) key vint(val-len) val
func ReadAsByteOffs(fp sophie.FsPath) (buffer bytesp.Slice, keyOffs, keyEnds, valOffs, valEnds villa.IntSlice, ...)
func WriteByteOffs(fp sophie.FsPath, buffer []byte, keyOffs, keyEnds, valOffs, valEnds []int) error
type DirInput
type DirOutput
type Reader
type Writer
func ReadAsByteOffs(fp sophie .FsPath ) (buffer bytesp.Slice, keyOffs, keyEnds, valOffs, valEnds villa.IntSlice, err error )
ReadAsByteOffs reads a kv file as a slice of buffer and some int slices
of key offsets, key ends, value offsets, and value ends.
WriteByteOffs generates a kv file with key-value pairs represented as a
slice of buffer and some int slices of key offsets, key ends, value offsets,
and value ends.
A folder with KV Files as an mr.Input
A folder with KV Files as an Output
Clean removes the folder.
