Struct diesel::sql_types::Interval

[+] Show declaration

pub struct Interval;

[−] Expand description

The interval SQL type.

This type is currently only implemented for PostgreSQL.

ToSql impls

• PgInterval which can be constructed using IntervalDsl

FromSql impls

• PgInterval which can be constructed using IntervalDsl

Trait Implementations

impl Foldable for Interval

type Sum = Nullable<Interval>

The SQL type of sum(this_type)

type Avg = Nullable<Interval>

impl Sub for Interval

type Rhs = Interval

The SQL type which can be subtracted from this one

type Output = Interval

The SQL type of the result of subtracting Rhs from Self

impl Mul for Interval

type Rhs = Integer

The SQL type which this can be multiplied by

type Output = Interval

impl SqlOrd for Interval

impl QueryId for Interval

[+]

type QueryId = Interval

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool
