Description

Typechecking instance declarations

Synopsis

tcInstDecls1 :: [LInstDecl GhcRn] -> TcM (TcGblEnv, [InstInfo GhcRn], [DerivInfo], ThBindEnv)
tcInstDeclsDeriv :: [DerivInfo] -> [LDerivDecl GhcRn] -> TcM (TcGblEnv, [InstInfo GhcRn], HsValBinds GhcRn)
tcInstDecls2 :: [LTyClDecl GhcRn] -> [InstInfo GhcRn] -> TcM (LHsBinds GhcTc)

Documentation

tcInstDecls1 :: [LInstDecl GhcRn] -> TcM (TcGblEnv, [InstInfo GhcRn], [DerivInfo], ThBindEnv) Source #

tcInstDeclsDeriv :: [DerivInfo] -> [LDerivDecl GhcRn] -> TcM (TcGblEnv, [InstInfo GhcRn], HsValBinds GhcRn) Source #

Use DerivInfo for data family instances (produced by tcInstDecls1), datatype declarations (TyClDecl), and standalone deriving declarations (DerivDecl) to check and process all derived class instances.

tcInstDecls2 :: [LTyClDecl GhcRn] -> [InstInfo GhcRn] -> TcM (LHsBinds GhcTc) Source #
