Returns the display width of a string. Assumes all characters with unknown widths are 0 width.

utf8EncodedLength :: String -> Int

ghc-boot GHC.Utils.Encoding.UTF8

hexToInt :: String -> Int

dbus DBus.Internal.Address

fromLatin25 :: String -> Int

locators Data.Locator

Given a number encoded in Locator16, convert it back to an integer.

hashString :: String -> Int

hegg Data.Equality.Utils

Get the hash of a string. This util is currently used to generate an Int used for the internal pattern variable representation from the external pattern variable representation (String)

readInt :: String -> Int

ViennaRNAParser Bio.ViennaRNAParserLibrary

decodeunsigned :: String -> Int

gpolyline GPolyline

overflowError :: String -> a

bytestring Data.ByteString.Internal

Raises a SizeOverflowException, with a message using the given function name.

abort :: Partial => String -> a

safe Safe

Synonym for error. Used for instances where the program has decided to exit because of invalid user input, or the user pressed quit etc. This function allows error to be reserved for programmer errors.

fromString :: ConvertibleStrings String a => String -> a

string-conversions Data.String.Conversions.Monomorphic

bomb :: String -> a

polysemy Polysemy.Internal.Fixpoint

The error used in fixpointToFinal, runFixpoint and runFixpointM when the result of a failed computation is recursively used and somehow visible. You may use this for your own Fixpoint interpreters. The argument should be the name of the interpreter.

cabalBug :: String -> a

userBug :: String -> a

error' :: String -> a

simple-cmd SimpleCmd

Alias for errorWithoutStackTrace (for base >= 4.9)

succError :: String -> a

ihaskell IHaskellPrelude

predError :: String -> a

ihaskell IHaskellPrelude

error :: forall (r :: RuntimeRep) . forall (a :: TYPE r) . HasCallStack => String -> a

basement Basement.Imports

stop execution and displays an error message

errorUnsupported :: String -> a

streamly-core Streamly.Internal.Data.MutByteArray

clashCompileError :: forall a . HasCallStack => String -> a

clash-prelude Clash.Magic

Same as error but will make HDL generation fail if included in the final circuit. This is useful for the error case of static assertions. Note that the error message needs to be a literal, and during HDL generation the error message does not include a stack trace, so it had better be descriptive.

errorX :: HasCallStack => String -> a

clash-prelude Clash.XException

Like error, but throwing an XException instead of an ErrorCall The ShowX methods print these error-values as undefined; instead of error'ing out with an exception.

cudaError :: String -> a

cuda Foreign.CUDA.Driver.Error

Raise a CUDAException. Exceptions can be thrown from pure code, but can only be caught in the IO monad.

error :: forall (r :: RuntimeRep) (a :: TYPE r) . HasCallStack => String -> a

foundation Foundation

stop execution and displays an error message

nonBottomError :: String -> a

ChasingBottoms Test.ChasingBottoms.IsBottom

nonBottomError s raises an exception (AssertionFailed) that is not caught by isBottom. Use s to describe the exception.

abort :: String -> a

xmonad XMonad.StackSet

this function indicates to catch that an error is expected
