The Get type
A decoder procuced by running a
|Fail !ByteString String|
The decoder ran into an error. The decoder either used
|Partial (Maybe ByteString -> Decoder a)|
|Done !ByteString a|
The decoder has successfully finished. Except for the output value you also get the unused input.
|BytesRead !Int64 (Int64 -> Decoder a)|
The decoder needs to know the current position in the input. Given the number of bytes remaning in the decoder, the outer decoder runner needs to calculate the position and resume the decoding.
Return at least
n bytes, maybe more. If not enough data is available
the computation will escape with
Ensure that there are at least
n bytes available. If not, the
computation will escape with
Deprecated: This will force all remaining input, don't use it.
DEPRECATED. Get the number of bytes of remaining input. Note that this is an expensive function to use as in order to calculate how much input remains, all input has to be read and kept in-memory. The decoder keeps the input as a strict bytestring, so you are likely better off by calculating the remaining input in another way.
Deprecated: Use 'getByteString' instead of 'getBytes'.
DEPRECATED. Same as
Test whether all input has been consumed, i.e. there are no remaining undecoded bytes.
