Enum OptLevel 

pub enum OptLevel {
    None,
    Less,
    Default,
    Aggressive,
    Size,
    SizeMin,
}

Optimization level for code generation.

Variants

None

No optimizations (fastest compilation).

Less

Basic optimizations.

Default

Standard optimizations (default).

Aggressive

Aggressive optimizations.

Size

Size-optimized output.

SizeMin

Aggressively size-optimized output.

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

Formats the value using the given formatter.

impl Default for OptLevel

fn default() -> OptLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptLevel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for OptLevel

impl Hash for OptLevel

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 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 Serialize for OptLevel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
