Struct DeletionFile 

pub struct DeletionFile {
    pub file_type: i32,
    pub read_version: u64,
    pub id: u64,
    pub num_deleted_rows: u64,
    pub base_id: Option<u32>,
}

Deletion File

The path of the deletion file is constructed as: {root}/_deletions/{fragment_id}-{read_version}-{id}.{extension} where {extension} is .arrow or .bin depending on the type of deletion.

Fields

file_type: i32

Type of deletion file. If it is unspecified, then the remaining fields will be missing.

read_version: u64

The version of the dataset this deletion file was built from.

id: u64

An opaque id used to differentiate this file from others written by concurrent writers.

num_deleted_rows: u64

The number of rows that are marked as deleted.

base_id: Option<u32>

The base path index of the data file. Used when the file is imported or referred from another dataset. Lance use it as key of the base_paths field in Manifest to determine the actual base path of the data file.

Implementations

impl DeletionFile

pub fn file_type(&self) -> DeletionFileType

Returns the enum value of file_type, or the default if the field is set to an invalid enum value.

pub fn set_file_type(&mut self, value: DeletionFileType)

Sets file_type to the provided enum value.

pub fn base_id(&self) -> u32

Returns the value of base_id, or the default value if base_id is unset.

Trait Implementations

impl Clone for DeletionFile

fn clone(&self) -> DeletionFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeletionFile

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

Formats the value using the given formatter.

impl Default for DeletionFile

fn default() -> Self

Returns the “default value” for a type.

impl Message for DeletionFile

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 DeletionFile

const NAME: &'static str = "DeletionFile"

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.table"

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 DeletionFile

fn eq(&self, other: &DeletionFile) -> 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 TryFrom<DeletionFile> for DeletionFile

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: DeletionFile) -> Result<Self>

Performs the conversion.

impl Copy for DeletionFile

impl StructuralPartialEq for DeletionFile
