    type Owned: Debug + Clone + Sync + Send + AsRef<Self::Native>;

    fn validate(views: &[u128], buffers: &[Buffer]) -> Result<(), ArrowError>;
}

A trait over the variable length bytes view array types

Required Associated Types

type Native: ByteArrayNativeType + AsRef<Self::Native> + AsRef<[u8]> + ?Sized

Type for representing its equivalent rust type i.e Utf8Array will have native type has &str BinaryArray will have type as u8

type Owned: Debug + Clone + Sync + Send + AsRef<Self::Native>

Type for owned corresponding to Native

Required Associated Constants

const IS_UTF8: bool

If element in array is utf8 encoded string.

const PREFIX: &'static str

“Binary” or “String”, for use in displayed or error messages

Provided Associated Constants

const DATA_TYPE: DataType = _

Datatype of array elements

Required Methods

fn validate(views: &[u128], buffers: &[Buffer]) -> Result<(), ArrowError>

Verifies that the provided buffers are valid for this array type

Object Safety

This trait is not object safe.

Implementors

impl ByteViewType for BinaryViewType

const IS_UTF8: bool = false

const PREFIX: &'static str = "Binary"

type Native = [u8]

type Owned = Vec<u8>

impl ByteViewType for StringViewType

const IS_UTF8: bool = true

const PREFIX: &'static str = "String"

type Native = str

type Owned = String
