bounceback
An io.ReadSeeker and io.WriteSeeker that returns to the right place before
reading or writing. Useful when the same file resource is being reused for reads
or writes throughout that file.
list_files
A recursive path walker that supports filters.
seekable_buffer
A memory structure that satisfies io.ReadWriteSeeker.
copy_bytes_between_positions
Given an io.ReadWriteSeeker, copy N bytes from one position to an earlier
position.
read_counter, write_counter
Wrap io.Reader and io.Writer structs in order to report how many bytes were
transferred.
readseekwritecloser
Provides the ReadWriteSeekCloser interface that combines a RWS and a Closer. Also provides a no-op wrapper to augment a plain RWS with a closer.
boundedreadwriteseek
Wraps a ReadWriteSeeker such that no seeks can be at an offset less than a specific-offset.
calculateseek
Provides a reusable function with which to calculate seek offsets.
progress_wrapper
Provides io.Reader and io.Writer wrappers that also trigger callbacks after
each call. The reader wrapper also invokes the callback upon EOF.
does_exist
Check whether a file/directory exists using a file-path.
graceful_copy
Do a copy but correctly handle short-writes and reads that might return a non- zero read count and EOF.
readseeker_to_readerat
A wrapper that allows an io.ReadSeeker to be used as a io.ReaderAt.
simplefileinfo
An implementation of os.FileInfo to support testing.
