Text.Megaparsec.Byte.Binary

Binary-format number parsers.

Since: 9.2.0

Generic parsers

class BinaryChunk chunk where

Data types that can be converted to little- or big- endian numbers.

Methods

convertChunkBE :: (Bits a, Num a) => chunk -> a

convertChunkLE :: (Bits a, Num a) => chunk -> a

Instances

BinaryChunk ByteString

Defined in Text.Megaparsec.Byte.Binary

Methods

convertChunkBE :: (Bits a, Num a) => ByteString -> a

convertChunkLE :: (Bits a, Num a) => ByteString -> a

BinaryChunk ByteString

Defined in Text.Megaparsec.Byte.Binary

Methods

convertChunkBE :: (Bits a, Num a) => ByteString -> a

convertChunkLE :: (Bits a, Num a) => ByteString -> a

anyLE

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

anyBE

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

Parse a big-endian Word16.

word32le :: (MonadParsec e s m, BinaryChunk (Tokens s)) => m Word32

Parse a little-endian Word32.

word32be :: (MonadParsec e s m, BinaryChunk (Tokens s)) => m Word32
