valuerunParseASN1State :: ParseASN1 a -> [ASN1] -> Either String (a, [ASN1])

run the parse monad over a stream and returns the result and the remaining ASN1 Stream.

valuerunParseASN1 :: ParseASN1 a -> [ASN1] -> Either String a

run the parse monad over a stream and returns the result.

If there's still some asn1 object in the state after calling f, an error will be raised.

valuethrowParseError :: String -> ParseASN1 a

throw a parse error

9 declarations

valueonNextContainer :: ASN1ConstructionType -> ParseASN1 a -> ParseASN1 a

run a function of the next elements of a container of specified type

valueonNextContainerMaybe

just like onNextContainer, except it doesn't throw an error if the container doesn't exists.

valuegetNextContainer :: ASN1ConstructionType -> ParseASN1 [ASN1]

get next container of specified type and return all its elements

valuegetNextContainerMaybe :: ASN1ConstructionType -> ParseASN1 (Maybe [ASN1])

just like getNextContainer, except it doesn't throw an error if the container doesn't exists.

valuegetNext :: ParseASN1 ASN1

get next element from the stream

valuegetNextMaybe :: (ASN1 -> Maybe a) -> ParseASN1 (Maybe a)

get next element from the stream maybe

valuehasNext :: ParseASN1 Bool

returns if there's more elements in the stream.

valuegetObject :: ASN1Object a => ParseASN1 a

get next object

valuegetMany :: ParseASN1 a -> ParseASN1 [a]

get many elements until there's nothing left
