Implementations

impl OptLevel

pub fn all() -> &'static [OptLevel]

Returns a slice with all possible OptLevel values.

Trait Implementations

impl Clone for OptLevel

fn clone(&self) -> OptLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptLevel

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

Formats the value using the given formatter.

impl Display for OptLevel

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

Formats the value using the given formatter.

impl FromStr for OptLevel

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<OptLevel, <OptLevel as FromStr>::Err>

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

impl Hash for OptLevel

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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.
