Operator that copies the contents of a database to file(s)

Fields

input: Arc<LogicalPlan>

The relation that determines the tuples to write to the output file(s)

output_url: String

The location to write the file(s)

partition_by: Vec<String>

Determines which, if any, columns should be used for hive-style partitioned writes

file_type: Arc<dyn FileType>

File type trait

options: HashMap<String, String>

SQL Options that can affect the formats

Trait Implementations

impl Clone for CopyTo

fn clone(&self) -> CopyTo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CopyTo

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

Formats the value using the given formatter.

impl Hash for CopyTo

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 CopyTo

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