Struct datafusion_expr::logical_plan::dml::CopyTo

pub struct CopyTo {
    pub input: Arc<LogicalPlan>,
    pub output_url: String,
    pub file_format: FileType,
    pub single_file_output: bool,
    pub copy_options: CopyOptions,
}

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)

file_format: FileType

The file format to output (explicitly defined or inferred from file extension)

single_file_output: bool

If false, it is assumed output_url is a file to which all data should be written regardless of input partitioning. Otherwise, output_url is assumed to be a directory to which each output partition is written to its own output file

copy_options: CopyOptions

Arbitrary options as tuples

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 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<CopyTo> for CopyTo

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