Represents a tombstone (deleted file) in the Delta log.

Fields

path: String

A relative path to a data file from the root of the table or an absolute path to a file that should be added to the table. The path is a URI as specified by RFC 2396 URI Generic Syntax, which needs to be decoded to get the data file path.

data_change: bool

When false the logical file must already be present in the table or the records in the added file must be contained in one or more remove actions in the same version.

deletion_timestamp: Option<i64>

The time this logical file was created, as milliseconds since the epoch.

extended_file_metadata: Option<bool>

When true the fields partition_values, size, and tags are present

partition_values: Option<HashMap<String, Option<String>>>

A map from partition column to value for this logical file.

size: Option<i64>

The size of this data file in bytes

tags: Option<HashMap<String, Option<String>>>

Map containing metadata about this logical file.

deletion_vector: Option<DeletionVectorDescriptor>

Information about deletion vector (DV) associated with this add action

base_row_id: Option<i64>

Default generated Row ID of the first row in the file. The default generated Row IDs of the other rows in the file can be reconstructed by adding the physical index of the row within the file to the base Row ID

default_row_commit_version: Option<i64>

First commit version in which an add action with the same path was committed to the table.

Trait Implementations

impl Borrow<str> for Remove

Borrow Remove as str so we can look at tombstones hashset in DeltaTableState by using a path from action Add.

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for Remove

fn clone(&self) -> Remove

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Remove

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

Formats the value using the given formatter.

impl Default for Remove

fn default() -> Remove

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Remove

fn deserialize<__D>( __deserializer: __D ) -> Result<Remove, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Remove> for Action

fn from(a: Remove) -> Action

Converts to this type from the input type.

impl Hash for Remove

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Remove

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Remove

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Remove
