type Attribute func(context.Context) context.Context

func Bool

func Bool(k string, b bool) Attribute

func Float32

func Float32(k string, f float32) Attribute

func Float64

func Float64(k string, f float64) Attribute

func Int16

func Int16(k string, i int16) Attribute

func Int32

func Int32(k string, i int32) Attribute

func Uint16

func Uint16(k string, u uint16) Attribute

func Uint32

func Uint32(k string, u uint32) Attribute

func Uint8

type Done

type Done func(*context.Context, *error)

func Impure

func Impure(ctx context.Context) (context.Context, Done)

Impure will initiate a new span that can encounter an error during operation

func Operation

func Operation(ctx context.Context, operation string) (context.Context, Done)

Operation will bootstrap a short lived code path and report traces, metrics, and logs automatically.

An operation is assumed to have some failure condition due to side effects.

type NoErrDone

type NoErrDone func(*context.Context)

func Pure

func Pure(ctx context.Context) (context.Context, NoErrDone)

Pure will initiate a new span that cannot encounter an error during operation
