haskell - How does one pipe `rawRequestBody` into `requestBodySource`? -

-

yesod has rawrequestbody following type signature:

rawrequestbody :: monadhandler m => source m bytestring

and http-conduit has function converts source requestbody:

requestbodysource :: int64 -> source (resourcet io) bytestring -> requestbody

i want able stream rawrequestbody s3 object converting requestbody inside handler, resourcet io ~ monadhandler doesn't compute , can't seem monadhandler m => m -> resourcet io

i've tried:

transpipe - if source handler bytestring rawrequestbody seems way @ bytestring consume it, i.e 

transpipe ??? rawrequestbody :: source (resourcet io) bytestring

handlertoio - seems request body cleared there won't data available

please :)

the function wairequest give wai request value. can use sourcerequestbody source that.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
