By design, Go doesn't offer any mechanism for Exception handling. But Programmers from different backgrounds like Java, C++, Php can be sceptical about the decision. Exception handling with Try Catch Finally is well adapted in all the modern languages. To ease the pain, this library offers utility functions for Exception Handling, which will help programmers to write Go code with Try-Catch-Finally approach.
This is how you can throw Exception and handle within Catch:
import(
e "github.com/rbrahul/exception"
)
...e.Try(func() {
data:=getValue() // get me the value from Allionsifdata!=100 {
e.Throw(e.AssertionError("Expected value is not same as 100"))
}
})
.Catch(e.In(e.AssertionErrorType, e.ValueErrorType), func(excep*Exception) {
fmt.Println("Message:",excep.Message)
fmt.Println("Exception Type:",excep.Type)
fmt.Println("Here is the Stack Trace:",excep.StackTrace)
})
.Catch(nil, func(excep*Exception) {
fmt.Println("I'll be executed as fallback:",excep.Message)
})
.Finally(func() {
fmt.Println("I have been executing always to clean the world!")
})
.Run()
...
Throwing a custom exception
You have to define a exception variable with ExceptionType.
