Installation

$ go get -u github.com/amirhsn/witherrors

Usage

Below is the detail of how to use this module with listed features. Firstly we need to import this modules.

import er "github.com/amirhsn/witherrors"

New Error

Same as built in go error which is create new error that takes one string parameter.

newErr := er.NewError("this is new error") 

Wrap Error

Wrap existing error to be passed into witherrors struct attribute.

_, err := redis.HDEL(.....)
return er.WrapError(err)

Error

Get error message as string data type, this is implementation of built in Error() in Go.

_, err := redis.HDEL(.....)
myError := er.WrapError(err)
errMessage := myError.Error()

With Code

Set error code as a string data type.

_, err := redis.HDEL(.....)
return er.WrapError(err).WithCode("CODE-1")

With Custom Message

Set error custom message as an empty interface data type.

_, err := redis.HDEL(.....)
return er.WrapError(err).WithCode("CODE-1").WithCustomMessage("Custom Message")

With Dependency

Set error dependency as a string data type.

_, err := redis.HDEL(.....)
return er.WrapError(err).WithCode("CODE-1").WithCustomMessage("Custom Message").WithDependency("MONGO")

With Priority

Set error priority as a Priority data type

_, err := redis.HDEL(.....)
return er.WrapError(err).WithCode("CODE-1").WithPriority(er.HIGH)

This method will receive Priority data type which is consist of 5 values listed below.

• VERY_LOW
• LOW
• MEDIUM
• HIGH
• VERY_HIGH

Get Code

Get error code as a string data type, if no code is set, message object will return empty code message.

_, err := redis.HDEL(.....)
myError := er.WrapError(err).WithCode("CODE-1")
code := myError.GetCode()

Get Custom Message

Get custom message error as an empty interface data type, if no custom message is set, message object will return empty custom message.

_, err := redis.HDEL(.....)
myError := er.WrapError(err).WithCustomMessage("custom")
cMessage := myError.GetCustomMessage()

Get Dependency

Get error dependency as a string data type, if no dependency is set, message object will return empty dependency message.

_, err := redis.HDEL(.....)
myError := er.WrapError(err).WithDependency("MONGO")
dep := myError.GetDependency()

Get Error

Get error as an error data type, if no error is set, message object will return empty error message.

_, err := redis.HDEL(.....)
myError := er.WrapError(err)
newError := myError.GetError()

Get Message

Get message as a string data type. Remember that this is not error message, but message because of empty get operation as mentioned above.

_, err := redis.HDEL(.....)
myError := er.WrapError(err)
message := myError.GetMessage()

Get Priority

Get error priority as a string data type, if no priority is set, message object will return empty priority message.

_, err := redis.HDEL(.....)
myError := er.WrapError(err).WithPriority(er.HIGH)
priority := er.GetPriority()

Clear

Clear all existing data (code, dependency, priority, custom message).

_, err := redis.HDEL(.....)
myError := er.WrapError(err)
myError.Clear()

Clear And Get

Clear all existing data (code, dependency, priority, custom message).

_, err := redis.HDEL(.....)
myError := er.WrapError(err)
clearedErr := myError.ClearAndGet().WithCustomMessage("new err")
