Module diesel::pg::data_types[][src]

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
