Struct diesel::pg::data_types::PgInterval

source ·
pub struct PgInterval {
    pub microseconds: i64,
    pub days: i32,
    pub months: i32,
}
Available on crate feature postgres_backend only.
Expand description

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.

Fields§

§microseconds: i64

The number of whole microseconds

§days: i32

The number of whole days

§months: i32

The number of whole months

Implementations§

source§

impl PgInterval

source

pub fn new(microseconds: i64, days: i32, months: i32) -> Self

Constructs a new PgInterval

No conversion occurs on the arguments. It is valid to provide a number of microseconds greater than the longest possible day, or a number of days greater than the longest possible month, as it is impossible to say how many months are in “40 days” without knowing a precise date.

source

pub fn from_microseconds(microseconds: i64) -> Self

Equivalent to new(microseconds, 0, 0)

source

pub fn from_days(days: i32) -> Self

Equivalent to new(0, days, 0)

source

pub fn from_months(months: i32) -> Self

Equivalent to new(0, 0, months)
