Available on crate feature postgres_backend only.

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

• Cents
  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.
• PgDate
  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.
• PgInterval
  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.
• PgMoney
  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.
• PgTime
  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.
• PgTimestamp
  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

• PgNumeric
  Represents a NUMERIC value, closely mirroring the PG wire protocol representation
