Enum InvariantLevel 

pub enum InvariantLevel {
    Always,
    Executable,
}

Variants

Always

Invariants that are always true in DataFusion LogicalPlans such as the number of expected children and no duplicated output fields

Executable

Invariants that must hold true for the plan to be “executable” such as the type and number of function arguments are correct and that wildcards have been expanded

To ensure a LogicalPlan satisfies the Executable invariants, run the Analyzer

Trait Implementations

impl Clone for InvariantLevel

fn clone(&self) -> InvariantLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvariantLevel

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

Formats the value using the given formatter.

impl Hash for InvariantLevel

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 InvariantLevel

fn eq(&self, other: &InvariantLevel) -> 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 InvariantLevel

fn partial_cmp(&self, other: &InvariantLevel) -> 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.
