Struct diesel::sql_types::Range

pub struct Range<ST: 'static>(/* private fields */);

Available on crate feature postgres_backend only.

The Range SQL type.

This wraps another type to represent a SQL range of that type.

ToSql impls

• (Bound<T>, Bound<T>) for any T which implements ToSql<ST>.

FromSql impls

• (Bound<T>, Bound<T>) for any T which implements FromSql<ST>.

Trait Implementations

impl<'a, ST: 'static, T> AsExpression<Range<ST>> for &'a (Bound<T>, Bound<T>)

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<ST: Clone + 'static> Clone for Range<ST>

fn clone(&self) -> Range<ST>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<ST: Debug + 'static> Debug for Range<ST>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<ST: Default + 'static> Default for Range<ST>

fn default() -> Range<ST>

Returns the “default value” for a type.

impl<T, ST> FromSql<Range<ST>, Pg> for (Bound<T>, Bound<T>)

where T: FromSql<ST, Pg>,

fn from_sql(value: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<DB::RawValue<'_>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl HasSqlType<Range<BigInt>> for Pg

fn metadata(_: &mut Self::MetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

impl HasSqlType<Range<Date>> for Pg

fn metadata(_: &mut Self::MetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

impl<ST: 'static + QueryId> QueryId for Range<ST>

type QueryId = Range<<ST as QueryId>::QueryId>

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool = _

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.

where T: FromSql<ST, Pg>,

type Row = (Bound<T>, Bound<T>)

The Rust type you’d like to map from.

fn build(row: Self) -> Result<Self>

Construct an instance of this type

impl<ST: 'static> SqlType for Range<ST>

type IsNull = NotNull

Is this type nullable?

where T: ToSql<ST, Pg>,

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, Pg>) -> Result

See the trait documentation.
