Enum OptimizationLevel 

pub enum OptimizationLevel {
    None,
    Basic,
    Standard,
    Aggressive,
}

Optimization level controlling aggressiveness of optimizations.

Variants

None

No optimizations (O0)

Basic

Basic optimizations (O1): constant folding, simple simplifications

Standard

Standard optimizations (O2): includes algebraic laws, normal forms

Aggressive

Aggressive optimizations (O3): all transformations, multiple passes

Trait Implementations

impl Clone for OptimizationLevel

fn clone(&self) -> OptimizationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizationLevel

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

Formats the value using the given formatter.

impl Default for OptimizationLevel

fn default() -> OptimizationLevel

Returns the “default value” for a type.

impl Ord for OptimizationLevel

fn cmp(&self, other: &OptimizationLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OptimizationLevel

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

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