Struct OwnedRow

pub struct OwnedRow(Box<[Option<ScalarImpl>]>);

An owned row type with a Vec<Datum>.

Tuple Fields

0: Box<[Option<ScalarImpl>]>

Implementations

impl OwnedRow

pub fn empty() -> OwnedRow

Returns an empty row.

Note: use empty if possible.

pub fn new(values: Vec<Option<ScalarImpl>>) -> OwnedRow

pub fn into_inner(self) -> Box<[Option<ScalarImpl>]>

Retrieve the underlying [Box<[Datum]>].

pub fn as_inner(&self) -> &[Option<ScalarImpl>]

pub fn from_pretty_with_tys(tys: &[DataType], s: impl AsRef<str>) -> OwnedRow

Parse an OwnedRow from a pretty string, only used in tests.

pub fn last(&self) -> Option<ScalarRefImpl<'_>>

Trait Implementations

impl AsRef<OwnedRow> for OwnedRow

fn as_ref(&self) -> &OwnedRow

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for OwnedRow

fn clone(&self) -> OwnedRow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedRow

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

Formats the value using the given formatter.

impl Default for OwnedRow

fn default() -> OwnedRow

Returns the “default value” for a type.

impl EstimateSize for OwnedRow

fn estimated_heap_size(&self) -> usize

The estimated heap size of the current struct in bytes.

fn estimated_size(&self) -> usize

where Self: Sized,

The estimated total size of the current struct in bytes, including the estimated_heap_size and the size of Self.

impl FromIterator<Option<ScalarImpl>> for OwnedRow

fn from_iter<T>(iter: T) -> OwnedRow

where T: IntoIterator<Item = Option<ScalarImpl>>,

Creates a value from an iterator.

impl Hash for OwnedRow

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Index<usize> for OwnedRow

Do not implement IndexMut to make it immutable.

type Output = Option<ScalarImpl>

The returned type after indexing.

fn index(&self, index: usize) -> &<OwnedRow as Index<usize>>::Output

Performs the indexing (container[index]) operation.

impl IntoIterator for OwnedRow

type IntoIter = IntoIter<Option<ScalarImpl>>

Which kind of iterator are we turning this into?

type Item = Option<ScalarImpl>

The type of the elements being iterated over.

fn into_iter(self) -> <OwnedRow as IntoIterator>::IntoIter

Creates an iterator from a value.

impl PartialEq for OwnedRow

fn eq(&self, other: &OwnedRow) -> 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 Row for OwnedRow

fn datum_at(&self, index: usize) -> Option<ScalarRefImpl<'_>>

Returns the DatumRef at the given index.

unsafe fn datum_at_unchecked(&self, index: usize) -> Option<ScalarRefImpl<'_>>

Returns the DatumRef at the given index without bounds checking.

fn len(&self) -> usize

Returns the number of datum in the row.

fn iter(&self) -> impl ExactSizeIterator

Returns an iterator over the datums in the row, in DatumRef form.

fn to_owned_row(&self) -> OwnedRow

Converts the row into an OwnedRow.

fn into_owned_row(self) -> OwnedRow

Consumes self and converts it into an OwnedRow.

fn is_empty(&self) -> bool

Returns true if the row contains no datum.

fn value_serialize_into(&self, buf: impl BufMut)

Serializes the row with value encoding, into the given buf.

fn value_serialize(&self) -> Vec<u8>

Serializes the row with value encoding and returns the bytes.

fn value_serialize_bytes(&self) -> Bytes

Serializes the row with value encoding and returns the bytes.

fn value_estimate_size(&self) -> usize

fn memcmp_serialize_into(&self, serde: &OrderedRowSerde, buf: impl BufMut)

Serializes the row with memcomparable encoding, into the given buf. As each datum may have different order type, a serde should be provided.

fn memcmp_serialize(&self, serde: &OrderedRowSerde) -> Vec<u8>

Serializes the row with memcomparable encoding and return the bytes. As each datum may have different order type, a serde should be provided.

fn hash_datums_into<H>(&self, state: &mut H)

where H: Hasher,

Hash the datums of this row into the given hasher.

fn hash<H>(&self, hash_builder: H) -> HashCode<H>

where H: BuildHasher,

Returns the hash code of the row.

fn eq(this: &Self, other: impl Row) -> bool

Determines whether the datums of this row are equal to those of another.

impl Eq for OwnedRow
