CaptureHost takes a host:port and returns the host.

CheckHostnameIPMismatch checks for a hostname/IP mismatch in a map of hosts to host:ports.

CheckLocalMissing checks a slice of host:ports for the given local host:port, return an error if not found, otherwise nil.

HostPortsByHost parses a list of host/port conbinations and creates a map of unique hosts each containing a slice of the hostsport instances for each host.

Min returns the lowest integer and is defined because golang only has a min function for floats and not for ints.

MS returns the number of milliseconds given in a duration.

SelectBool takes an option and a default value and returns the default value if the option is equal to the zero value, and the option otherwise.

SelectDuration takes an option and a default value and returns the default value if the option is equal to zero, and the option otherwise.

SelectFloat takes an option and a default value and returns the default value if the option is equal to zero, and the option otherwise.

SelectInt takes an option and a default value and returns the default value if the option is equal to zero, and the option otherwise.

ShuffleStrings takes a slice of strings and returns a new slice containing the same strings in a random order.

ShuffleStringsInPlace uses the Fisher–Yates shuffle to randomize the strings in place.

SingleNodeCluster determines if hostport is the only host:port contained within the hostMap.

StringInSlice returns whether the string is contained within the slice.

TakeNode takes an element from nodes at the given index, or at a random index if index < 0.

TimeNowMS returns Unix time in milliseconds for time.Now().

TimeZero returns a time such that time.IsZero() is true.

UnixMS returns Unix time in milliseconds for the given time.

HostportPattern is regex to match a host:port.

Timestamp is a bi-directional binding of Time to interger Unix timestamp in JSON.
