Language.Haskell.TH.Lift.Internal

Description

Helper functions used in code that Language.Haskell.TH.Lift generates.

Note: this is an internal module, and as such, the API presented here is not guaranteed to be stable, even between minor releases of this library.

Synopsis

errorQuoteExp :: Quote q => String -> q Exp
unsafeSpliceCoerce :: forall a m. Quote m => m Exp -> Code m a

Documentation

errorQuoteExp :: Quote q => String -> q Exp Source #

A type-restricted version of error that ensures makeLift always returns a value of type q Exp (where q is an instance of Quote), even when used on an empty datatype.

unsafeSpliceCoerce :: forall a m. Quote m => m Exp -> Code m a Source #

This is a cargo-culted version of unsafeSpliceCoerce from the th-compat library, which has been copied here to avoid incurring a library dependency.

Only available when built with template-haskell-2.9.0.0 or later.
