Generic parsers
class BinaryChunk chunk where Source #
Data types that can be converted to little- or big- endian numbers.
Methods
convertChunkBE :: (Bits a, Num a) => chunk -> a Source #
convertChunkLE :: (Bits a, Num a) => chunk -> a Source #
Instances

Arguments
| :: forall a e s m. (MonadParsec e s m, FiniteBits a, Num a, BinaryChunk (Tokens s)) | |
| => Maybe String | Label, if any |
| -> m a |
Parse a little-endian number.
You may wish to call this with a visible type application:
number <- anyLE (Just "little-endian 32 bit word") @Word32
Arguments
| :: forall a e s m. (MonadParsec e s m, FiniteBits a, Num a, BinaryChunk (Tokens s)) | |
| => Maybe String | Label, if any |
| -> m a |
Parse a big-endian number.
You may wish to call this with a visible type application:
number <- anyBE (Just "big-endian 32 bit word") @Word32
