Module re_sdk::external::arrow2::scalar

contains the Scalar trait object representing individual items of Arrays, as well as concrete implementations such as BooleanScalar.

Structs

• BinaryScalar
  The Scalar implementation of binary (Option<Vec<u8>>).
• BooleanScalar
  The Scalar implementation of a boolean.
• DictionaryScalar
  The DictionaryArray equivalent of Array for Scalar.
• FixedSizeBinaryScalar
  The Scalar implementation of fixed size binary ([Option<Box<[u8]>>]).
• FixedSizeListScalar
  The scalar equivalent of FixedSizeListArray. Like FixedSizeListArray, this struct holds a dynamically-typed Array. The only difference is that this has only one element.
• ListScalar
  The scalar equivalent of ListArray. Like ListArray, this struct holds a dynamically-typed Array. The only difference is that this has only one element.
• MapScalar
  The scalar equivalent of MapArray. Like MapArray, this struct holds a dynamically-typed Array. The only difference is that this has only one element.
• NullScalar
  The representation of a single entry of a crate::array::NullArray.
• PrimitiveScalar
  The implementation of Scalar for primitive, semantically equivalent to Option<T> with DataType.
• StructScalar
  A single entry of a crate::array::StructArray.
• UnionScalar
  A single entry of a crate::array::UnionArray.
• Utf8Scalar
  The implementation of Scalar for utf8, semantically equivalent to Option<String>.

Traits

• Scalar
  Trait object declaring an optional value with a DataType. This trait is often used in APIs that accept multiple scalar types.

Functions

• new_scalar
  creates a new Scalar from an Array.
