Enum datafusion_expr::logical_plan::dml::CopyOptions

pub enum CopyOptions {
    SQLOptions(StatementOptions),
    WriterOptions(Box<FileTypeWriterOptions>),
}

When the logical plan is constructed from SQL, CopyOptions will contain arbitrary string tuples which must be parsed into FileTypeWriterOptions. When the logical plan is constructed directly from rust code (such as via the DataFrame API), FileTypeWriterOptions can be provided directly, avoiding the run time cost and fallibility of parsing string based options.

Variants

SQLOptions(StatementOptions)

Holds StatementOptions parsed from a SQL statement

WriterOptions(Box<FileTypeWriterOptions>)

Holds FileTypeWriterOptions directly provided

Trait Implementations

impl Clone for CopyOptions

fn clone(&self) -> CopyOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for CopyOptions

fn hash<H>(&self, hasher: &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<CopyOptions> for CopyOptions

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