Struct BlobLayout 

pub struct BlobLayout {
    pub inner_layout: Option<Box<PageLayout>>,
    pub layers: Vec<i32>,
}

A layout where large binary data is encoded externally and only the descriptions (position + size) are placed in the page

Repdef information is stored in the descriptions. A description with a size of 0 and a position of 0 is an empty value. A description with a size of 0 and a non-zero position is a null value and the position is the repdef value.

Fields

inner_layout: Option<Box<PageLayout>>

The inner layout used to store the descriptions

layers: Vec<i32>

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

The inner layout’s repdef layers will always be 1 all valid item layer

Implementations

impl BlobLayout

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 BlobLayout

fn clone(&self) -> BlobLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlobLayout

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

Formats the value using the given formatter.

impl Default for BlobLayout

fn default() -> Self

Returns the “default value” for a type.

impl Message for BlobLayout

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 BlobLayout

const NAME: &'static str = "BlobLayout"

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.encodings21"

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 BlobLayout

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