Struct DeletionFile

pub struct DeletionFile {
    pub file_type: i32,
    pub read_version: u64,
    pub id: u64,
    pub num_deleted_rows: u64,
}

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.

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.

Trait Implementations

impl Clone for DeletionFile

fn clone(&self) -> DeletionFile

Returns a copy 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

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.
