Package conductor is a small helper to execute work heavy operations in the backgrounds that deliver partial results ("result streaming").

Package log implements utility methods for logging in a colorful manner.

Package trie implements a general purpose Path-*Node.

Clamp limits x to the range [lo, hi].

Closer closes c.

CopyFile simply copies the file at `src` to `dst`.

DeriveKey derives a key from password and salt being keyLen bytes long.

FindFreePort asks the operating system for a free port.

LimitWriter is like io.LimitReader but for an io.Writer.

Max returns the maximum of a and b.

Max64 returns the maximum of a and b.

Min returns the minimum of a and b.

Min64 returns the minimum of a and b.

NewTimeoutReader wraps `r` and returns a io.Reader that times out after `d` elapsed with ErrTimeout if `r` didn't succeed in that time.

NewTimeoutReadWriter wraps `rw` and returns a io.ReadWriter that times out after `d` elapsed with ErrTimeout if `rw` didn't succeed in that time.

NewTimeoutWriter wraps `w` and returns a io.Writer that times out after `d` elapsed with ErrTimeout if `w` didn't succeed in that time.

NopWriteCloser returns a WriteCloser with a no-op Close method wrapping the provided Writer w.

OmitBytes converts a byte slice into a string representation that omits data in the middle if necessary.

PeekHeader returns a new reader that will yield the very same data as `r`.

SyncedReadWriter returns a io.ReadWriter that protects each call to Read() and Write() with a sync.Mutex.

Tar packs all files in the directory pointed to by `root` and writes a gzipped and tarred version of it to `w`.

Touch works like the unix touch(1).

UClamp limits x to the range [lo, hi].

UMax returns the unsigned minimum of a and b.

UMin returns the unsigned minimum of a and b.

Untar reads .tar data (from Tar()) from `r` and writes all files packed in it to `root`.

ErrTimeout will be returned by Read/Write in case of a timeout.

Empty is just an empty struct.

SizeAccumulator is a io.Writer that simply counts the amount of bytes that has been written to it.

SyncBuffer is a bytes.Buffer that protects each call to Read() and Write() with a sync.RWMutex, i.e.

TimeoutReadWriter is io.ReadWriter capable of returning ErrTimeout if there was no result in a certain timeout period.

Errors is a list of errors that render to one single message.
