data RequestType Source #
Type of a request
Constructors

| WriteRequest | Request for |
Instances
data Precision ty where Source #
Predefined set of time precision.
RFC3339 is only available for QueryRequests.
Constructors
| Nanosecond :: Precision ty | POSIX time in ns |
| Microsecond :: Precision ty | POSIX time in μs |
| Millisecond :: Precision ty | POSIX time in ms |
| Second :: Precision ty | POSIX time in s |
| Minute :: Precision ty | POSIX time in minutes |
| Hour :: Precision ty | POSIX time in hours |
| RFC3339 :: Precision QueryRequest | Nanosecond precision time in a human readable format, like
|
precisionName :: Precision ty -> Text Source #
class Timestamp time where Source #
A Timestamp is something that can be converted to a valid
InfluxDB timestamp, which is represented as a 64-bit integer.
precisionScale :: Fractional a => Precision ty -> a Source #
data InfluxException Source #
Exceptions used in this library.
In general, the library tries to convert exceptions from the dependent libraries to the following types of errors.
Constructors
| ServerError String | Server side error. You can expect to get a successful response once the issue is resolved on the server side. |
| BadRequest String Request | Client side error. You need to fix your query to get a successful response. |
| IllformedJSON String ByteString | Unexpected JSON response. This can happen e.g. when the response from InfluxDB is incompatible with what this library expects due to an upstream format change etc. |

Instances
| HasPrecision QueryRequest QueryParams Source # | Returning JSON responses contain timestamps in the specified precision/format.
|
| HasPrecision WriteRequest WriteParams Source # | Timestamp precision. In the UDP API, all timestamps are sent in nanosecond but you can specify lower precision. The writer just rounds timestamps to the specified precision. |

class HasManager a where Source #

Methods
manager :: Lens' a (Either ManagerSettings Manager) Source #
HTTP manager settings or a manager itself.
If it's set to ManagerSettings, the library will create a Manager from
the settings for you.
