Struct diesel::sql_types::Interval

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
chrono::Duration with feature = "chrono"

§`FromSql` impls

PgInterval which can be constructed using IntervalDsl
chrono::Duration with feature = "chrono" (There might be some information loss due to special behavior for literal month (or longer) intervals; Please read official documentation of PostgreSQL Interval.)
