Get number of optimization passes

pub fn description(&self) -> &'static str

Get description

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 FromStr for OptimizationLevel

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

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.
