parseResultsWith

Arguments

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

A parser that takes

1. an optional name of the series
2. a map of tags
3. an array of field names
4. an array of values

to construct a value.

-> Value

-> Parser (Vector a)

Parse a JSON response

parseResultsWithDecoder

Arguments

:: Decoder a

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

A parser that takes

1. an optional name of the series
2. a map of tags
3. an array of field names
4. an array of values

to construct a value.

-> Value

-> Parser (Vector a)

Parse a JSON response with specified 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

Fail immediately if there's any parse failure.

lenientDecoder :: Decoder a

Ignore parse failures and return successful results.

getField

Arguments

:: Text

Column name

-> Vector Text

Columns

-> Array

Fields

-> Parser Value

Get a field value from a column name

getTag

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

Parse either a POSIX timestamp or RFC3339 formatted timestamp.

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

Parse an integer POSIX timestamp in given time precision.

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

Parse a RFC3339-formatted timestamp.

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

parseResultsObject :: Value -> Parser (Vector Value)

parseSeriesObject :: Value -> Parser (Vector Value)
