Parser

data Parser

data ParserCallbacks

Each callback should return True to continue parsing, or False to cancel.

Constructors

ParserCallbacks

Fields

parsedNull :: IO Bool

parsedBoolean :: Bool -> IO Bool

parsedNumber :: ByteString -> IO Bool

parsedText :: Text -> IO Bool

parsedBeginArray :: IO Bool

parsedEndArray :: IO Bool

parsedBeginObject :: IO Bool

parsedAttributeName :: Text -> IO Bool

parsedEndObject :: IO Bool

data ParseStatus

Constructors

ParseFinished

ParseContinue

More input is required before parsing can complete.

ParseCancelled

A callback returned False.

ParseError Text

An error occured while parsing. The included message contains details about the error.

Instances

Eq ParseStatus

Show ParseStatus

newParser :: ParserCallbacks -> IO Parser

parseUTF8 :: Parser -> ByteString -> IO ParseStatus

parseText :: Parser -> Text -> IO ParseStatus

parseComplete :: Parser -> IO ParseStatus

Indicate that no more input is available, and parse any remaining buffered input.

getBytesConsumed :: Parser -> IO Integer

Get the number of bytes consumed from the last input chunk.

Note that if using parseText, this corresponds to UTF-8 bytes, not characters.

If the most recent call to parseUTF8 or parseText returned ParseFinished, this will indicate whether there are any un-parsed bytes past the end of input.

If the most recent parse returned ParseError, this will indicate where the error occured.

Generator

data Generator

data GeneratorConfig

Constructors

GeneratorConfig

Fields

generatorBeautify :: Bool

Whether to generate indented, whitespaced output.

generatorIndent :: Text

How much to indent beautified output by. This is only used if generatorBeautify is True.

data GeneratorError

If an error is encountered when generating data, a GeneratorError will be thrown.

With the exception of MaximumDepthExceeded, this is usually due to incorrect use of the library.

Constructors

InvalidAttributeName

MaximumDepthExceeded

GeneratorInErrorState

GenerationComplete

InvalidNumber

NoBuffer

Instances

Eq GeneratorError

Show GeneratorError

Typeable GeneratorError

Exception GeneratorError

newGenerator :: GeneratorConfig -> IO Generator

Create a new, empty generator with the given configuration.

getBuffer :: Generator -> IO ByteString

Retrieve the NUL-terminated byte buffer.

clearBuffer :: Generator -> IO ()

Clear the generator's output buffer. This does not change the state of the generator.
