mft

some tools (golang)

ID Generator

struct *mft.G - generator next id
field G.AddValue - adds value that adds to each generated id use it with *G.RvGetPart() method
valid values for G.AddValue: 10 - 9990 step 10
method *G.RvGetPart() - returns ids as time.Now().UnixNano() / 10000 * 10000 + AddValue[10-9990; s10] + tail[0-9]
method *G.RvGet() - returns ids as time.Now().UnixNano() / 10000 * 10000 + AddValue + tail[unbounded]
*G.RvGet() faster then *G.RvGetPart() however does not provide uniqueness between generators when using different G.AddValue

Global generator

mft.GlobalGenerator.AddValue = 100 sets global AddValue as 100
mft.RvGet() generates next id
mft.RvGetPart() generates next id uniqueness between generators when using different mft.GlobalGenerator.AddValue

Error

You can create error with code and error from error

Flags

mft.FillCallStack = true - enables call stack

Error codes

Use mft.AddErrorsCodes(m) for append error codes
Use mft.GenerateError(code, params...) for create error with code
Use mft.GenerateErrorE(m) for create error with code from another error
Use mft.GenerateErrorSubList(m) for create error with code from errors list

Example:

package main
import (
	"fmt"
	"github.com/myfantasy/mft"
)
func main() {
	var e error
	e = mft.ErrorCS(7, "Bond Error")
	fmt.Println(e)
	e = mft.ErrorCSE(12, "M Error", e)
	fmt.Println(e)
}

[7] Bond Error
[12] M Error    [7] Bond Error
