setHandlers :: LogHandler a => [a] -> Logger -> Logger

hslogger System.Log.Logger

Set the Logger's list of handlers to the list supplied. All existing handlers are removed first.
setLevel :: Priority -> Logger -> Logger

hslogger System.Log.Logger

Sets the "level" of the Logger. Returns a new Logger object with the new level.
setElem :: a -> (Int, Int) -> Matrix a -> Matrix a

matrix Data.Matrix

Replace the value of a cell in a matrix.
setSize :: a -> Int -> Int -> Matrix a -> Matrix a

matrix Data.Matrix

Set the size of a matrix to given parameters. Use a default element for undefined entries if the matrix has been extended.
setContentLength :: Word64 -> Response -> Response

snap-core Snap.Core

A note here: if you want to set the Content-Length for the response, Snap forces you to do it with this function rather than by setting it in the headers; the Content-Length in the headers will be ignored. The reason for this is that Snap needs to look up the value of Content-Length for each request, and looking the string value up in the headers and parsing the number out of the text will be too expensive. If you don't set a content length in your response, HTTP keep-alive will be disabled for HTTP/1.0 clients, forcing a Connection: close. For HTTP/1.1 clients, Snap will switch to the chunked transfer encoding if Content-Length is not specified. Example:
```
ghci> setContentLength 400 emptyResponse
HTTP/1.1 200 OK
Content-Length: 400
```

setContentType :: ByteString -> Response -> Response

snap-core	Snap.Core

Sets the Content-Type in the Response headers. Example:

ghci> :set -XOverloadedStrings
ghci> setContentType "text/html" emptyResponse
HTTP/1.1 200 OK
content-type: text/html

setHeader :: HasHeaders a => CI ByteString -> ByteString -> a -> a

snap-core Snap.Core

Sets a header key-value-pair in a HasHeaders datatype. If a header with the same name already exists, it is overwritten with the new value. Example:
```
ghci> import qualified Snap.Types.Headers as H
ghci> setHeader "Host" "localhost" H.empty
H {unH = [("host","localhost")]}
ghci> setHeader "Host" "127.0.0.1" it
H {unH = [("host","127.0.0.1")]}
```

setResponseBody :: (OutputStream Builder -> IO (OutputStream Builder)) -> Response -> Response

snap-core	Snap.Core

Sets an HTTP response body to the given stream procedure. Example:

ghci> :set -XOverloadedStrings
ghci> import qualified System.IO.Streams as Streams
ghci> import qualified Data.ByteString.Builder as Builder
ghci> :{
ghci| let r = setResponseBody
ghci|         (out -> do
ghci|             Streams.write (Just $ Builder.byteString "Hello, world!") out
ghci|             return out)
ghci|         emptyResponse
ghci| :}
ghci> r
HTTP/1.1 200 OK

Hello, world!

setResponseCode :: Int -> Response -> Response

snap-core Snap.Core

Sets the HTTP response code. Example:
```
ghci> setResponseCode 404 emptyResponse
HTTP/1.1 404 Not Found
```
setResponseStatus :: Int -> ByteString -> Response -> Response

snap-core Snap.Core

Sets the HTTP response status. Note: normally you would use setResponseCode unless you needed a custom response explanation. Example:
```
ghci> :set -XOverloadedStrings
ghci> setResponseStatus 500 "Internal Server Error" emptyResponse
HTTP/1.1 500 Internal Server Error
```
