Enum RewriteStrategy 

pub enum RewriteStrategy {
    OnePass,
    Exhaustive,
    FixedPoint {
        max_iterations: usize,
    },
    Prioritized,
    BottomUp,
    TopDown,
}

Strategy for applying rewrite rules.

Variants

OnePass

Apply each rule once to each node

Exhaustive

Apply rules until no more matches found

FixedPoint

Apply rules in a fixed-point manner (until convergence)

Fields

max_iterations: usize

Prioritized

Apply rules in order of priority

BottomUp

Apply rules bottom-up (from leaves to root)

TopDown

Apply rules top-down (from root to leaves)

Trait Implementations

impl Clone for RewriteStrategy

fn clone(&self) -> RewriteStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RewriteStrategy

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

Formats the value using the given formatter.

impl Default for RewriteStrategy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RewriteStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RewriteStrategy

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 RewriteStrategy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RewriteStrategy
