Struct diesel::sql_types::Interval

pub struct Interval;

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 SqlOrd for Interval

impl Foldable for Interval

type Sum = Nullable<Interval>

The SQL type of sum(this_type)

type Avg = Nullable<Interval>

The SQL type of avg(this_type)

impl QueryId for Interval

type QueryId = Interval

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl NotNull for Interval

impl SingleValue for Interval

impl HasSqlType<Interval> for Pg

fn metadata(_: &PgMetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

fn row_metadata(
    out: &mut Vec<Self::TypeMetadata>,
    lookup: &Self::MetadataLookup
)

impl Debug for Interval

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Interval

fn clone(&self) -> Interval

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
