Constants

const DDTagsDelimiter = ":"

DDTagsDelimiter is the separator between key-val pairs for DD env vars

const OtelTagsDelimeter = "="

OtelTagsDelimeter is the separator between key-val pairs for OTEL env vars

Functions

func BoolEnv

func BoolEnv(key string, def bool) bool

BoolEnv returns the parsed boolean value of an environment variable, or def otherwise.

func BoolVal

func BoolVal(val string, def bool) bool

BoolVal returns the parsed boolean value of string val, or def if not parseable

func DurationEnv

func DurationEnv(key string, def time.Duration) time.Duration

DurationEnv returns the parsed duration value of an environment variable, or def otherwise.

func FloatEnv

func FloatEnv(key string, def float64) float64

FloatEnv returns the parsed float64 value of an environment variable, or def otherwise.

func ForEachStringTag

func ForEachStringTag(str string, delimiter string, fn func(key string, val string))

ForEachStringTag runs fn on every key val pair encountered in str. str may contain multiple key val pairs separated by either space or comma (but not a mixture of both), and each key val pair is separated by a delimiter.

func IntEnv

func IntEnv(key string, def int) int

IntEnv returns the parsed int value of an environment variable, or def otherwise.

func ParseTagString

func ParseTagString(str string) map[string]string

ParseTagString returns tags parsed from string as map

Types

type LockMap

type LockMap struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

LockMap uses an RWMutex to synchronize map access to allow for concurrent access. This should not be used for cases with heavy write load and performance concerns.

func NewLockMap

func NewLockMap(m map[string]string) *LockMap

func (*LockMap) Clear

func (l *LockMap) Clear()

func (*LockMap) Get

func (l *LockMap) Get(k string) string

func (*LockMap) Iter

func (l *LockMap) Iter(f func(key string, val string))

Iter iterates over all the map entries passing in keys and values to provided func f. Note this is READ ONLY.

func (*LockMap) Len

func (l *LockMap) Len() int

func (*LockMap) Set

func (l *LockMap) Set(k, v string)

type MetaStructValue

type MetaStructValue struct {
	Value any // TODO: further constraining Value's type, especially if it becomes public
}

MetaStructValue is a custom type wrapper used to send metadata to the agent via the `meta_struct` field instead of the `meta` inside a span.
