Struct DatumContainer 

pub struct DatumContainer { /* private fields */ }

Container wrapping BytesContainer that traffics only in Row-formatted bytes.

This type accepts only Row-formatted bytes in its Push implementation, and in return provides a DatumSeq view of the bytes which can be decoded as Datums.

Implementations

impl DatumContainer

pub fn heap_size(&self, callback: impl FnMut(usize, usize))

Visit contained allocations to determine their size and capacity.

Trait Implementations

impl BatchContainer for DatumContainer

type Owned = Row

An owned instance of Self::ReadItem<'_>.

type ReadItem<'a> = DatumSeq<'a>

The type that can be read back out of the container.

fn into_owned<'a>(item: Self::ReadItem<'a>) -> Self::Owned

Conversion from an instance of this type to the owned type.

fn clone_onto<'a>(item: Self::ReadItem<'a>, other: &mut Self::Owned)

Clones self onto an existing instance of the owned type.

fn push_ref(&mut self, item: Self::ReadItem<'_>)

Push an item into this container

fn push_own(&mut self, item: &Self::Owned)

Push an item into this container

fn clear(&mut self)

Clears the container. May not release resources.

fn with_capacity(size: usize) -> Self

Creates a new container with sufficient capacity.

fn merge_capacity(cont1: &Self, cont2: &Self) -> Self

Creates a new container with sufficient capacity.

fn reborrow<'b, 'a: 'b>(item: Self::ReadItem<'a>) -> Self::ReadItem<'b>

Converts a read item into one with a narrower lifetime.

fn index(&self, index: usize) -> Self::ReadItem<'_>

Reference to the element at this position.

fn len(&self) -> usize

Number of contained elements

fn get(&self, index: usize) -> Option<Self::ReadItem<'_>>

Reference to the element at this position, if it exists.

fn last(&self) -> Option<Self::ReadItem<'_>>

Returns the last item if the container is non-empty.

fn is_empty(&self) -> bool

Indicates if the length is zero.

fn advance<F>(&self, start: usize, end: usize, function: F) -> usize

where F: for<'a> Fn(Self::ReadItem<'a>) -> bool,

Reports the number of elements satisfying the predicate.

impl PushInto<&Row> for DatumContainer

fn push_into(&mut self, item: &Row)

Push item into self.

impl PushInto<DatumSeq<'_>> for DatumContainer

fn push_into(&mut self, item: DatumSeq<'_>)
