Module diesel::pg::data_types
source · [−]Expand description
Data structures for PG types which have no corresponding Rust type
Most of these types are used to implement ToSql
and FromSql
for higher
level types.
Structs
Money is represented in Postgres as a 64 bit signed integer. This struct is a dumb wrapper
type, meant only to indicate the integer’s meaning. The fractional precision of the value is
determined by the lc_monetary
setting of the database.
This struct is re-exported as Cents
as a convenient and conventional expression of a typical
unit of 1/100th of currency. For other names or precisions, users might consider a differently
named use
of the PgMoney
struct.
Dates are represented in Postgres as a 32 bit signed integer representing the number of julian days since January 1st 2000. This struct is a dumb wrapper type, meant only to indicate the integer’s meaning.
Intervals in Postgres are separated into 3 parts. A 64 bit integer representing time in microseconds, a 32 bit integer representing number of days, and a 32 bit integer representing number of months. This struct is a dumb wrapper type, meant only to indicate the meaning of these parts.

Time is represented in Postgres as a 64 bit signed integer representing the number of microseconds since midnight. This struct is a dumb wrapper type, meant only to indicate the integer’s meaning.
Timestamps are represented in Postgres as a 64 bit signed integer representing the number of microseconds since January 1st 2000. This struct is a dumb wrapper type, meant only to indicate the integer’s meaning.
Enums
Represents a NUMERIC value, closely mirroring the PG wire protocol representation
