Enum AcrossPartitions

pub enum AcrossPartitions {
    Heterogeneous,
    Uniform(Option<ScalarValue>),
}

Represents whether a constant expression’s value is uniform or varies across partitions. Has two variants:

• Heterogeneous: The constant expression may have different values for different partitions.
• Uniform(Option<ScalarValue>): The constant expression has the same value across all partitions, or is None if the value is unknown.

Variants

Heterogeneous

Uniform(Option<ScalarValue>)

Trait Implementations

impl Clone for AcrossPartitions

fn clone(&self) -> AcrossPartitions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AcrossPartitions

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

Formats the value using the given formatter.

impl Default for AcrossPartitions

fn default() -> AcrossPartitions

Returns the “default value” for a type.

impl Display for AcrossPartitions

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

Formats the value using the given formatter.

impl PartialEq for AcrossPartitions

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