pub struct Interval;
Expand description
The interval SQL type.
This type is currently only implemented for PostgreSQL.
§ToSql
impls
PgInterval
which can be constructed usingIntervalDsl
chrono::Duration
withfeature = "chrono"
§FromSql
impls
PgInterval
which can be constructed usingIntervalDsl
chrono::Duration
withfeature = "chrono"
(There might be some information loss due to special behavior for literalmonth
(or longer) intervals; Please read official documentation of PostgreSQL Interval.)
