Fields

input_columns: Option<Option<Vec<String>>>

image: Option<Option<String>>

Docker image to use for the UDF (optional)

udf: Option<Option<String>>

Base64 encoded pickled UDF (optional)

udf_name: Option<Option<String>>

Name of the UDF (optional)

udf_version: Option<Option<String>>

Version of the UDF (optional)

udf_backend: Option<Option<String>>

UDF backend type (e.g. DockerUDFSpecV1) (optional)

auto_backfill: Option<Option<bool>>

Whether to automatically backfill the column (optional)

manifest: Option<Option<String>>

JSON-serialized manifest for the UDF environment (optional)

manifest_checksum: Option<Option<String>>

SHA-256 checksum of the manifest content (optional)

field_metadata: Option<HashMap<String, String>>

User-supplied field metadata (optional)

Implementations

impl AlterVirtualColumnEntry

pub fn new() -> AlterVirtualColumnEntry

Trait Implementations

impl Clone for AlterVirtualColumnEntry

fn clone(&self) -> AlterVirtualColumnEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlterVirtualColumnEntry

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

Formats the value using the given formatter.

impl Default for AlterVirtualColumnEntry

fn default() -> AlterVirtualColumnEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AlterVirtualColumnEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AlterVirtualColumnEntry

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

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.
