FastStringEnv

Synopsis

FastString environments (maps)

type FastStringEnv a = UniqFM a Source #

A non-deterministic set of FastStrings. See Note [Deterministic UniqFM] in UniqDFM for explanation why it's not deterministic and why it matters. Use DFastStringEnv if the set eventually gets converted into a list or folded over in a way where the order changes the generated code.

Manipulating these environments

extendFsEnv_C :: (a -> a -> a) -> FastStringEnv a -> FastString -> a -> FastStringEnv a Source #

extendFsEnv_Acc :: (a -> b -> b) -> (a -> b) -> FastStringEnv b -> FastString -> a -> FastStringEnv b Source #

extendFsEnvList_C :: (a -> a -> a) -> FastStringEnv a -> [(FastString, a)] -> FastStringEnv a Source #

mapFsEnv :: (elt1 -> elt2) -> FastStringEnv elt1 -> FastStringEnv elt2 Source #
