Fields

input_columns: Vec<String>

List of input Lance field paths for the virtual column. Nested fields use dot-separated segments; use backtick-quoted segments for literal dots and double backticks inside quoted segments.

outputs: Vec<AddVirtualColumnOutputEntry>

Output columns produced by the virtual column UDF

image: String

Docker image to use for the UDF

udf: String

Base64 encoded pickled UDF

udf_name: String

Name of the UDF

udf_version: String

Version of the UDF

udf_backend: Option<Option<String>>

UDF backend type (e.g. DockerUDFSpecV1)

auto_backfill: Option<Option<bool>>

Whether to automatically backfill the column after creation

manifest: Option<Option<String>>

JSON-serialized manifest for the UDF environment

manifest_checksum: Option<Option<String>>

SHA-256 checksum of the manifest content

field_metadata: Option<HashMap<String, String>>

User-supplied field metadata (string key-value pairs)

Implementations

impl AddVirtualColumnEntry

pub fn new( input_columns: Vec<String>, outputs: Vec<AddVirtualColumnOutputEntry>, image: String, udf: String, udf_name: String, udf_version: String, ) -> AddVirtualColumnEntry

Trait Implementations

impl Clone for AddVirtualColumnEntry

fn clone(&self) -> AddVirtualColumnEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddVirtualColumnEntry

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

Formats the value using the given formatter.

impl Default for AddVirtualColumnEntry

fn default() -> AddVirtualColumnEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AddVirtualColumnEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AddVirtualColumnEntry

fn eq(&self, other: &AddVirtualColumnEntry) -> 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 Serialize for AddVirtualColumnEntry

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.
