TuiError

Holds a terminal error: a code and what was being attempted.

Syntax

type TuiError
    as int32 code       '' TuiErrorCode
    as string detail
    declare function Message( ) as string
end type

Description

The error carried by every Result in the module. Errors exist only at the terminal layer: drawing never fails, and lookups return Optional instead.

Example

#import "std/numeric"
#import "std/tui"
using tui, numeric

dim as TuiError e = TuiError( TUIERR_NOTATTY, "stdout is not a console", 0 )
print e.code = TUIERR_NOTATTY      '' -1 (true)
print e.detail                    '' stdout is not a console
print len( e.Message( ) ) > 0      '' -1 (true)
