Creates an in memory table.

Fields

name: OwnedTableReference

The table name

constraints: Constraints

The list of constraints in the schema, such as primary key, unique, etc.

input: Arc<LogicalPlan>

The logical plan

if_not_exists: bool

Option to not error if table already exists

or_replace: bool

Option to replace table content if table already exists

column_defaults: Vec<(String, Expr)>

Default values for columns

Trait Implementations

impl Clone for CreateMemoryTable

fn clone(&self) -> CreateMemoryTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Hash for CreateMemoryTable

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 CreateMemoryTable

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