They used qualified imports:
import qualified Data.ByteString as ByteString
import qualified Data.Map.Strict as Map
So everything from “Data.ByteString” has to be prefixed with “ByteString.”
In real-world code, depending on conventions, you’d probably add unqualified imports for the type names to avoid the needless duplication:
import Data.ByteString (ByteString)
import Data.Map.Strict (Map)
import qualified Data.ByteString as ByteString
import qualified Data.Map.Strict as Map
type Chan = Map Int ByteString
pushMsg =
…
let inserted = Map.insert …
- buckie 10y agoAlso, `ByteString` as the qualified name is a bit unusual but it probably is helpful for clarifying what's going on for people unfamiliar with Haskell. I'm more used to seeing: import Data.ByteString (ByteString) import qualified Data.ByteString as BS import qualified Data.ByesString.Lazy as BSL import qualified Data.ByteString.Char8 as BSC
