Error

The Error class is used to handle errors in Mojo.

init

We are able to initialize empty errors, with custom messages and even with string references.

var err : Error = Error()
raise err

warning: Expression [3]:22:5: unreachable code after raise statement
    return
    ^



Error:

var custom_err : Error = Error("my custom error")
raise custom_err

warning: Expression [4]:22:5: unreachable code after raise statement
    return
    ^



Error: my custom error

var ref : StringRef = StringRef("hello")
var err : Error = Error(ref)

raise err

warning: Expression [7]:24:5: unreachable code after raise statement
    return
    ^



Error: hello

var err : Error = Error("something is wrong")
print(err.value)

something is wrong

Allows error to be copied.

var err : Error = Error("hey")
var other : Error = err

raise other

warning: Expression [8]:25:5: unreachable code after raise statement
    return
    ^



Error: hey
