Struct CopyTo 

pub struct CopyTo {
    pub input: Arc<LogicalPlan>,
    pub output_url: String,
    pub partition_by: Vec<String>,
    pub file_type: Arc<dyn FileType>,
    pub options: HashMap<String, String>,
    pub output_schema: DFSchemaRef,
}

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

output_schema: DFSchemaRef

The schema of the output (a single column “count”)

Implementations

impl CopyTo

pub fn new( input: Arc<LogicalPlan>, output_url: String, partition_by: Vec<String>, file_type: Arc<dyn FileType>, options: HashMap<String, String>, ) -> Self

Trait Implementations

impl Clone for CopyTo

fn clone(&self) -> CopyTo

Returns a duplicate 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

Formats the value using the given formatter.

impl Hash for CopyTo

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

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: &Self) -> 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 PartialOrd for CopyTo

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
