Trait ByteViewType

pub trait ByteViewType:
    Sealed
    + 'static
    + PartialEq
    + Send
    + Sync {
    type Native: ByteArrayNativeType + AsRef<Self::Native> + AsRef<[u8]> + ?Sized;

    const DATA_TYPE: DataType = _;

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

A trait over the variable length bytes view array types

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 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 Methods

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

Verifies that the provided buffers are valid for this array type

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so 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
