GHC.Types.SafeHaskell

Description

This stuff here is related to supporting the Safe Haskell extension, primarily about storing under what trust type a module has been compiled.

Synopsis

- type IsSafeImport = Bool
- data SafeHaskellMode
  - = Sf_None
  - | Sf_Unsafe
  - | Sf_Trustworthy
  - | Sf_Safe
  - | Sf_SafeInferred
  - | Sf_Ignore
- data IfaceTrustInfo
- getSafeMode :: IfaceTrustInfo -> SafeHaskellMode
- setSafeMode :: SafeHaskellMode -> IfaceTrustInfo
- noIfaceTrustInfo :: IfaceTrustInfo

# Documentation

type IsSafeImport = Bool Source #

Is an import a safe import?

data SafeHaskellMode Source #

The various Safe Haskell modes

Constructors

Sf_None | inferred unsafe
Sf_Unsafe | declared and checked
Sf_Trustworthy | declared and checked
Sf_Safe | declared and checked
Sf_SafeInferred | inferred as safe
Sf_Ignore | `-fno-safe-haskell` state
