Description
Final zonking to Type. See Note [Zonking to Type].

Zonking
For a description of "zonking", see Note [What is zonking?].
type ZonkTcM = ZonkT TcM Source #
Zonking monad for a computation that zonks to Type, reading from a ZonkEnv
but not extending or modifying it.
See Note [Zonking to Type].
zonkTopDecls :: Bag EvBind -> LHsBinds GhcTc -> [LRuleDecl GhcTc] -> [LTcSpecPrag] -> [LForeignDecl GhcTc] -> TcM (TypeEnv, Bag EvBind, LHsBinds GhcTc, [LForeignDecl GhcTc], [LTcSpecPrag], [LRuleDecl GhcTc]) Source #
zonkTyBndrsX :: [TcTyVar] -> ZonkBndrTcM [TcTyVar] Source #
zonkTcTypeToType :: TcType -> TcM Type Source #

zonkTyVarOcc :: HasDebugCallStack => TcTyVar -> ZonkTcM Type Source #
zonkTcEvBinds :: TcEvBinds -> ZonkBndrTcM TcEvBinds Source #
ZonkEnv, and the ZonkT and ZonkBndrT monad transformers
module GHC.Tc.Zonk.Env
Coercion holes
isFilledCoercionHole :: CoercionHole -> TcM Bool Source #
Is a coercion hole filled in?
unpackCoercionHole :: CoercionHole -> TcM Coercion Source #
Retrieve the contents of a coercion hole. Panics if the hole is unfilled
unpackCoercionHole_maybe :: CoercionHole -> TcM (Maybe Coercion) Source #
Retrieve the contents of a coercion hole, if it is filled
Rewriter sets
zonkRewriterSet :: RewriterSet -> TcM RewriterSet Source #
Check whether any coercion hole in a RewriterSet is still unsolved. Does this by recursively looking through filled coercion holes until one is found that is not yet filled in, at which point this aborts.
