Type Alias VectorRef 

pub type VectorRef<'a> = VectorInner<&'a [VectorItemType]>;

Aliased Type

pub struct VectorRef<'a> {
    pub(crate) inner: &'a [OrderedFloat<f32>],
}

Fields

inner: &'a [OrderedFloat<f32>]

Implementations

impl<'a> VectorRef<'a>

pub fn from_slice_unchecked(inner: &'a [VectorItemType]) -> Self

Create a VectorRef from a slice of VectorItemType without checking the elements in the slice is invalid, such as inf and nan.

pub fn memcmp_serialize( self, serializer: &mut Serializer<impl BufMut>, ) -> Result<()>

pub fn subvector(&self, start: usize, end: usize) -> VectorVal

Trait Implementations

impl Debug for VectorRef<'_>

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

Formats the value using the given formatter.

impl<'a> ScalarRef<'a> for VectorRef<'a>

type ScalarType = VectorInner<Box<[OrderedFloat<f32>]>>

ScalarType is the owned type of current ScalarRef.

fn to_owned_scalar(&self) -> VectorVal

Convert ScalarRef to an owned scalar.

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

A wrapped hash function to get the hash value for this scaler.

impl ToText for VectorRef<'_>

fn write<W: Write>(&self, f: &mut W) -> Result

Write the text to the writer regardless of its data type

fn write_with_type<W: Write>(&self, _ty: &DataType, f: &mut W) -> Result

Write the text to the writer according to its data type

fn to_text_with_type(&self, ty: &DataType) -> String

Convert to text according to its data type

fn to_text(&self) -> String

to_text is a special version of to_text_with_type, it convert the scalar to default type text. E.g. for Int64, it will convert to text as a Int64 type. We should prefer to use to_text_with_type because it’s more clear and readable.

fn text_display(&self) -> impl Display + '_

Returns an displayable wrapper implemented with ToText::write.

impl<'scalar> TryFrom<ScalarRefImpl<'scalar>> for VectorRef<'scalar>

type Error = ArrayError

The type returned in the event of a conversion error.

fn try_from(val: ScalarRefImpl<'scalar>) -> ArrayResult<Self>

Performs the conversion.
