Struct FullZipLayout

pub struct FullZipLayout {
    pub bits_rep: u32,
    pub bits_def: u32,
    pub value_compression: Option<ArrayEncoding>,
    pub layers: Vec<i32>,
}

/ A layout used for pages where the data is large / / In this case the cost of transposing the data is relatively small (compared to the cost of writing the data) / and so we just zip the buffers together

Fields

bits_rep: u32

The number of bits of repetition info (0 if there is no repetition)

bits_def: u32

The number of bits of definition info (0 if there is no definition)

value_compression: Option<ArrayEncoding>

Description of the compression of values

layers: Vec<i32>

The meaning of each repdef layer, used to interpret repdef buffers correctly

Implementations

impl FullZipLayout

pub fn layers( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(_: i32) -> Option<RepDefLayer>>

Returns an iterator which yields the valid enum values contained in layers.

pub fn push_layers(&mut self, value: RepDefLayer)

Appends the provided enum value to layers.

Trait Implementations

impl Clone for FullZipLayout

fn clone(&self) -> FullZipLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FullZipLayout

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

Formats the value using the given formatter.

impl Default for FullZipLayout

fn default() -> Self

Returns the “default value” for a type.

impl Message for FullZipLayout

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl Name for FullZipLayout

const NAME: &'static str = "FullZipLayout"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "lance.encodings"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for FullZipLayout

fn eq(&self, other: &FullZipLayout) -> 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.
