Enum OptLevel 

#[repr(u8)]
pub enum OptLevel {
    O0 = 0,
    O1 = 1,
    O2 = 2,
    O3 = 3,
}

Optimization level for the compiler.

Variants

O0 = 0

No optimizations.

O1 = 1

Conservative optimizations (default).

O2 = 2

Aggressive optimizations.

O3 = 3

Maximum optimizations (size may increase).

Implementations

impl OptLevel

pub fn is_optimizing(self) -> bool

Returns true if any optimizations are enabled.

pub fn inline_enabled(self) -> bool

Returns true if inlining is enabled at this optimization level.

Trait Implementations

impl Clone for OptLevel

fn clone(&self) -> OptLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OptLevel

impl Debug for OptLevel

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

Formats the value using the given formatter.

impl Default for OptLevel

fn default() -> OptLevel

Returns the “default value” for a type.

impl Eq for OptLevel

impl Ord for OptLevel

fn cmp(&self, other: &OptLevel) -> 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 OptLevel

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

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