Struct PgRange 

pub struct PgRange<T> {
    pub lower: RangeBound<T>,
    pub upper: RangeBound<T>,
    pub is_empty: bool,
    pub range_oid: Oid,
    pub element_oid: Oid,
}

PostgreSQL range type.

Generic over the element type T. The range_oid and element_oid must be provided since Rust generics cannot map to PG range OIDs automatically.

Fields

lower: RangeBound<T>

upper: RangeBound<T>

is_empty: bool

range_oid: Oid

element_oid: Oid

Implementations

impl<T> PgRange<T>

pub fn empty(range_oid: Oid, element_oid: Oid) -> Self

Create an empty range.

impl<T: FromSql> PgRange<T>

pub fn from_sql_with_oids( buf: &[u8], range_oid: Oid, element_oid: Oid, ) -> Result<Self>

Decode a range from binary format. Requires OIDs since generic types cannot determine them.

Trait Implementations

impl<T: Clone> Clone for PgRange<T>

fn clone(&self) -> PgRange<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for PgRange<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for PgRange<T>

fn eq(&self, other: &PgRange<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ToSql> ToSql for PgRange<T>

fn oid(&self) -> Oid

The PostgreSQL type OID for this Rust type.

fn to_sql(&self, buf: &mut BytesMut) -> Result<()>

Encode this value into PG binary format, appending to buf.

fn to_sql_vec(&self) -> Result<Vec<u8>>

Encode this value into a standalone byte vector for use as a bind parameter.

fn is_null(&self) -> bool

Returns true if this value represents SQL NULL.
