Enum GraphOptimization 

pub enum GraphOptimization {
    Disabled,
    Basic,
    Extended,
    All,
}

Graph optimization level requested from a backend.

Variants

Disabled

Disable graph rewrites.

Basic

Apply safe basic rewrites.

Extended

Apply extended rewrites.

All

Apply all backend-supported rewrites.

Trait Implementations

impl Clone for GraphOptimization

fn clone(&self) -> GraphOptimization

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphOptimization

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

Formats the value using the given formatter.

impl Default for GraphOptimization

fn default() -> GraphOptimization

Returns the “default value” for a type.

impl Hash for GraphOptimization

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 GraphOptimization

fn eq(&self, other: &GraphOptimization) -> 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.
