Struct mz_persist_types::codec_impls::VecU8Schema

pub struct VecU8Schema;

An implementation of Schema2 for Vec<u8>.

Trait Implementations

impl Clone for VecU8Schema

fn clone(&self) -> VecU8Schema

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VecU8Schema

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

Formats the value using the given formatter.

impl Default for VecU8Schema

fn default() -> VecU8Schema

Returns the “default value” for a type.

impl PartialEq for VecU8Schema

fn eq(&self, other: &VecU8Schema) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Schema2<Vec<u8>> for VecU8Schema

type ArrowColumn = GenericByteArray<GenericBinaryType<i32>>

The type of column we decode from, and encoder will finish into.

type Statistics = NoneStats

Statistics we collect for a schema of this type.

type Decoder = SimpleColumnarDecoder<Vec<u8>>

Type that is able to decode values of T from Self::ArrowColumn.

type Encoder = SimpleColumnarEncoder<Vec<u8>>

Type that is able to encoder values of T.

fn encoder(&self) -> Result<Self::Encoder, Error>

Returns a type that can encode values of T.

fn decoder(&self, col: Self::ArrowColumn) -> Result<Self::Decoder, Error>

Returns a type that is able to decode instances of T from the provider column.

fn decoder_any(&self, col: &dyn Array) -> Result<Self::Decoder, Error>

Returns a type that is able to decode instances of T from a type erased arrow::array::Array, erroring if the provided array is not Self::ArrowColumn.
