Missing predicate for "ResourceVanished" IOException/IOErrorType
IOErrorType
has a "ResourceVanished
" constructor: https://hackage.haskell.org/package/base-4.10.1.0/docs/src/GHC.IO.Exception.html#IOErrorType
But there is no way to detect this for an IOException
or IOErrorType
.
Here is some real-world code I found, where the author wants to catch "ResourceVanished
", but resorts to catching all IOException
: https://hackage.haskell.org/package/http-client-tls-0.3.5.1/docs/src/Network-HTTP-Client-TLS.html#convertConnection
Docs for hPutBuf
also mention the public existence of "ResourceVanished
": https://hackage.haskell.org/package/base-4.10.1.0/docs/GHC-IO-Handle.html#v:hPutBuf
Suggestion:
We need to add functions:
isResourceVanished :: IOError -> Bool
resourceVanishedErrorType :: IOErrorType
isResourceVanishedErrorType :: IOErrorType -> Bool
