Enum OptimizerPhase 

#[non_exhaustive]
pub enum OptimizerPhase {
    Logical,
    Physical,
    Both,
}

Phase at which an OptimizerRule runs.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Logical

Logical optimizer.

Physical

Physical optimizer.

Both

Both — the rule is applied at logical and physical phases.

Trait Implementations

impl Clone for OptimizerPhase

fn clone(&self) -> OptimizerPhase

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OptimizerPhase

impl Debug for OptimizerPhase

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

Formats the value using the given formatter.

impl Eq for OptimizerPhase

impl PartialEq for OptimizerPhase

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