const (
	// BOOL reflects true or false, designated 'T' or 'F'
	Bool = "bool"

	// COUNT is a numeric representation of a UINT_64 represented as either
	// a string of digits or a hex number. Note that hex numbers will begin
	// with the traditional 0x
	Count = "count"

	// INT is a numeric type representing an INT_64 represetned by a string
	// of digits preceded by either a '+' or a '-'. Note that INT may also
	// be expressed in hex and will maintain its leading sign ('-0xff')
	Int = "int"

	// DOUBLE is a numeric type representing a double-precision float.
	// Representation is a string of digits with an optional decimal point
	// as well as optional '+' or '-' proceeding the number. The number may
	// also be optionally scaled with e notation. So 1234 123.4 -123.4
	// +1.234 and .003E-23 are examples of valid double types.
	Double = "double"

	// TIME is a temporal type representing an absolute time. Until found
	// otherwise it will be assumed that all time values are UNIX-NANO.
	Time = "time"

	// INTERVAL is a temporal type representing relative time. An Interval
	// constant is represented by by a numeric constant followed by a time
	// unit which is one of usec, msec, sec, min, hr, or day. An 's' may
	// be appended to the unit so 3.5 min and 3.5mins represent the same
	// value. Finally an optional '-' negates an interval, denoting past
	// time. So -12 hr is read as "twelve hours in the past."
	Interval = "interval"

	// STRING is a type used to hold character string values.
	String = "string"

	// PATTERN is a type used to represent regular expressions. Pattern
	// documentation can be found at
	// http://flex.sourceforge.net/manual/Patterns.html
	Pattern = "pattern"

	// PORT is a type used to represent transport-level port numbers these
	// are typically represented as a number followed by one of /udp, /tcp,
	// /icmp, or /unkown.
	Port = "port"

	// ADDR is a type used to represent an IP address. IPv4 addresses are
	// represented in dotted quad notation. IPv6 addresses are written in
	// colon hex notation as outlined in RFC 2373 (including the mixed
	// notation which allows dotted quad IPv4 addresses in the lower 32
	// bits) and further placed into brackets. So [::ffff:192.168.1.100]
	// can be used to represent the IPv4 address 192.168.1.100.
	Addr = "addr"

	// SUBNET is a type used to represent a subnet in CIDR notation. So
	// 10.10.150.0/24 and [fe80::]/64 are valid subnets.
	Subnet = "subnet"

	// ENUM is a type allowing the specification of a set of related
	// values that have no further structure.
	Enum = "enum"

	// STRING_SET is a SET which contains STRINGs
	StringSet = "set[string]"

	// ENUM_SET is a SET which contains ENUMs

	// STRING_VECTOR is a VECTOR which contains STRINGs
	StringVector = "vector[string]"

	// INTERVAL_VECTOR is a VECTOR which contains INTERVALs
	IntervalVector = "vector[interval]"

	// FUNCTION represents a function type in bro script.
	Function = "function"

	// EVENT represents an event handler in bro script.
	Event = "event"

	// HOOK represents a bro script object best described as as the an
	// intersection of a function and an event.
	Hook = "hook"

	// A file object which can be written to, but not read from (which is a
	// limitation of bro script and has nothing to do with brosync).
	File = "file"

	// OPAQUE represents data whos type is intentionally hidden, but whose
	// values may be passed to certain bro script builtins.
	Opaque = "opaque"

	// ANY is used to bypass strong typing in bro script.
	Any = "any"
)

Further documentation on bros datatypes can be found on the bro website at: https://www.bro.org/sphinx/script-reference/types.html It is of value to note that many of these types have applications specific to bro script and will likely never be implemented as types with any meaning in ai-hunt.
