parseResultsWith Source #

Arguments

:: (Maybe Text -> HashMap Text Text -> Vector Text -> Array -> Parser a)

A parser that takes

an optional name of the series
a map of tags
an array of field names
an array of values

to construct a value.

-> Parser (Vector a)

Parse a JSON response

parseResultsWithDecoder Source #

Arguments

:: Decoder a
-> (Maybe Text -> HashMap Text Text -> Vector Text -> Array -> Parser a)	A parser that takes an optional name of the series a map of tags an array of field names an array of values to construct a value.
-> Value
-> Parser (Vector a)

Parse a JSON response with specified decoder settings.

Decoder settings

Constructors

Decoder
Fields decodeEach :: Parser a -> Parser b How to turn a parser for each element into another. For example, a failure can be turned into `Nothing`. decodeFold :: Parser (Vector b) -> Parser (Vector a) How to aggregate all results from `decodeEach` into a vector of results.

strictDecoder :: Decoder a Source #

Fail immediately if there's any parse failure.

lenientDecoder :: Decoder a Source #

Ignore parse failures and return successful results.

getField Source #

Arguments

:: Text	Column name
-> Vector Text	Columns
-> Array	Fields
-> Parser Value

Get a field value from a column name

getTag Source #

Arguments

:: Monad m
=> Text	Tag name
-> HashMap Text Text	Tags
-> m Text

Get a tag value from a tag name

parseTimestamp :: Precision ty -> Value -> Parser POSIXTime Source #

Parse either a POSIX timestamp or RFC3339 formatted timestamp.

parsePOSIXTime :: Precision ty -> Value -> Parser POSIXTime Source #

Parse an integer POSIX timestamp in given time precision.

parseRFC3339 :: ParseTime time => Value -> Parser time Source #

Parse a RFC3339-formatted timestamp.

Note that this parser is slow as it converts a Text input to a String before parsing.

parseFieldValue :: Value -> Parser FieldValue Source #

parseResultsObject :: Value -> Parser (Vector Value) Source #

parseSeriesObject :: Value -> Parser (Vector Value) Source #

parseSeriesBody :: Value -> Parser (Maybe Text, HashMap Text Text, Vector Text, Array) Source #
