Documentation

typeE a = a ->ByteString Source

A function for rendering a value into a byte string.

Numbers

int2 ::E (Either Int16 Word16)Source

int4 ::E (Either Int32 Word32)Source

int8 ::E (Either Int64 Word64)Source

float4 ::E Float Source

float8 ::E Double Source

numeric ::E Scientific Source

Text

char ::E Char Source

A UTF-8-encoded char.

Note that since it's UTF-8-encoded not a "char" but a "text" OID should be used with it.

text ::E (Either Text Text)Source

Either a strict or a lazy text.

bytea ::E (Either ByteString ByteString)Source

Either a strict or a lazy bytestring.

Date and Time

date ::E Day Source

time ::Bool ->E TimeOfDay Source

Encoding strategy depends on whether the server supportsinteger_datetimes.

timetz ::Bool ->E (TimeOfDay,TimeZone)Source

Encoding strategy depends on whether the server supportsinteger_datetimes.

timestamp ::Bool ->E LocalTime Source

timestamptz ::Bool ->E UTCTime Source

interval ::E DiffTime Source

Misc

bool ::E Bool Source

uuid ::E UUID Source

array ::E Data Source
